This page details the processes for the Ubuntu Package Archive Administrators team, and hopefully provides a decent guide for new members of the team.
Bugs should be filed against the appropriate packages, and the team subscribed (not assigned) to the bug.
The requests can be found at https://launchpad.net/~ubuntu-archive/+subscribedbugs.
Team members may assign bugs to themselves and mark them In Progress if they're working on them, or discussing them; to act as a lock on that request.
1. Client-side tools
We are transitioning towards client-side administration as the necessary facilities become available via the Launchpad API. To get hold of these tools:
$ bzr branch lp:ubuntu-archive-tools
2. Logging In
A few operations still require direct ssh access to pepo.canonical.com; accounts are provided to some members of the team. (We are transitioning away from direct shell access, so new team members will not get accounts here, thereby encouraging us to complete the transition more quickly.) Changes can only be made as the lp_archive user, to which you'll have sudo access.
So to begin:
$ ssh pepo $ sudo -u lp_archive -i
The -i is important as lp_archive's .bashrc sets the right environment variables and makes sure the directory with all of the tools is placed in the PATH.
3. NEW Processing
To work with the upload queue, you may either use the web interface or the queue API client in ubuntu-archive-tools. The API client should generally be faster and more flexible; in particular, it is not currently possible to override individual binaries using the web interface.
Both source packages and new binaries which have not yet been approved are not automatically accepted into the archive, but are instead held for checking and manual acceptance. Once accepted they'll be automatically approved from then on.
The current queue can be obtained with:
$ ./queue info
This is the NEW queue for the development series of Ubuntu by default; you can change the queue with -Q, the distro with -D and the release using -s. To list the UNAPPROVED queue for ubuntu/trusty, for example:
$ ./queue -s trusty -Q unapproved info
Packages are placed in the UNAPPROVED queue if they're uploaded to a closed distribution, and are usually security updates or similar; this should be checked with the uploader.
You can give an string argument after info which is interpreted as a substring match filter.
To obtain a report of the size of all the different queues for a particular release:
$ ./queue report
Back to the NEW queue for now, however. You'll see output that looks somewhat like this:
$ ./queue info Listing ubuntu/dapper (New) 4 ---------|----|----------------------|----------------------|--------------- 25324 | S- | diveintopython-zh | 5.4-0ubuntu1 | 3 minutes | * diveintopython-zh/5.4-0ubuntu1 Component: main Section: doc 25276 | -B | language-pack-kde-co | 1:6.06+20060427 | 2 hours 20 minutes | * language-pack-kde-co-base/1:6.06+20060427/i386 Component: main Section: translations Priority: OPTIONAL 23635 | -B | upbackup (i386) | 0.0.1 | 2 days | * upbackup/0.0.1/i386 Component: main Section: admin Priority: OPTIONAL | * upbackup_0.0.1_i386_translations.tar.gz Format: raw-translations 23712 | S- | gausssum | 1.0.3-2ubuntu1 | 45 hours | * gausssum/1.0.3-2ubuntu1 Component: main Section: science ---------|----|----------------------|----------------------|--------------- 4
The number at the start can be used with other commands instead of referring to a package by name. The next field shows you what is actually in the queue, "S-" means it's a new source and "-B" means it's a new binary. You then have the package name, the version and how long it's been in the queue.
New sources need to be checked to make sure they're well packaged, the licence details are correct and permissible for us to redistribute, etc. See Packaging new software, debian/copyright file and Debian's Reject FAQ. You can fetch a package from the queue for manual checking:
$ ./queue fetch 25324
Or, if you just want to print the URLs so that you can fetch them on a system with a faster network connection:
$ ./queue show-urls 25324
The source is now in the current directory and ready for checking. Any problems should result in the rejection of the package (also send a mail to the uploader explaining the reason and Cc firstname.lastname@example.org):
$ ./queue reject 25324
If the package is fine, you should next check that it's going to end up in the right part of the archive. On the next line of the info output, you have details about the different parts of the package, including which component, section, etc. it is expected to head into. One of the important jobs is making sure that this information is actually correct through the application of overrides.
To alter the overrides for a package, use:
$ ./queue override -c universe ubuntustudio-menu
Where the override can be -c <component>, -x <section>, and/or (for binary packages) -p <priority>. If you want to limit the override application to only source or only binary packages, use the --source or --binary option respectively.
Often a binary will be in the NEW queue because it is a shared library that has changed SONAME. In this case you'll probably want to check the existing overrides to make sure anything new matches. These can be found in /ubuntu/indices on Ubuntu mirrors.
Currently a special case of this are the kernel packages, which change package names with each ABI update and build many distinct binary packages in different sections. A helper tool has been written to apply overrides to the queue based on the packages that are currently published:
$ ./kernel-overrides [-s <sourcepackage>] <newabi>
Binary packages are not often rejected (they go into a black hole with no automatic notifications), so, check the .deb contains files, run lintian on it and file bugs when things are broken. The binaries also need to be put into universe etc as appropriate even if the source is already there.
If you're happy with a package, and the overrides are correct, accept it with:
$ ./queue accept 23712
You can also use ./queue accept binary-name which will accept it for all architectures.
3.1. partner archive
The Canonical partner archive, though not part of Ubuntu proper, is managed using the same tools and queues. As such, use the same procedures when processing partner packages. E.g. (notice 'Component: partner'):
$ ./queue -s hardy info Listing ubuntu/hardy (New) 2 ---------|----|----------------------|----------------------|--------------- 1370980 | S- | arkeia | 8.0.9-3 | 19 hours | * arkeia/8.0.9-3 Component: partner Section: utils 1370964 | S- | arkeia-amd64 | 8.0.9-3 | 19 hours | * arkeia-amd64/8.0.9-3 Component: partner Section: utils ---------|----|----------------------|----------------------|--------------- 2
Use -A ubuntu/partner to remove a package:
$ ./remove-package -m "request Brian Thomason" -A ubuntu/partner -s precise adobe-flashplugin
The rules governing package inclusion in partner are not the same as those for the main Ubuntu archive. See ExtensionRepositoryPolicy for the Technical Board's requirements regarding the contents of add-on repositories made available through the Software Sources interface.
4. Component Mismatches and Changing Overrides
Sadly packages just don't stay where they're put. SeedManagement details how packages get chosen for the main component, the various meta packages and presence on the CD. What it doesn't point out is that packages which fall out of the seeding process are destined for the universe component.
Every 30 minutes or so, the difference between what the seeds expect to be true and what the archive actually believes is evaluated by the component-mismatches tool, and the output placed at:
This is split into four sections:
Source and binary promotions to main
These are source packages currently in universe that appear to need promoting to main. The usual reasons are that they are seeded, or that a package they build has become a dependency or build-dependency of a package in main. New sources need to be processed through the UbuntuMainInclusionQueue, and have been approved before they should be promoted. Also ensure that all of their dependencies (which will be in this list) are approved as well.
Binary only promotions to main
These are binary packages currently in universe that appear to need promoting to main, as above; except that their source package is already in main. An inclusion report isn't generally needed, though the package should be sanity checked. Especially check that all of the package's dependencies are already in main, or have been approved.
Source and binary demotions to universe
Sources and their binaries that are currently in main but are no longer seeded or depended on by another package. These either need to be seeded explicitly, or demoted.
Binary only demotions to universe
Binary packages in main that are no longer seeded or depended on, but the source is still to remain in main -- usually because another binary saves it. Often these tend to be -dev or -dbg packages and need to be seeded, rather than demoted; but not always.
Once you've determined what overrides need to be changed, use the change-override client-side tool to do it.
To promote a binary package to main:
$ ./change-override -c main git-email
To demote a source package and all of its binaries to universe:
$ ./change-override -c universe -S tspc
Less-used are the options to just move a source, and leave its binaries where it is (usually just to repair a mistaken forgotten -S):
$ ./change-override -c universe tspc ...oops, forgot the source... $ ./change-override -c universe -t tspc
and the option to move a binary and its source, but leave any other binaries where they are:
$ ./change-override -c universe -B flite
Sometimes packages just need removing entirely, because they are no longer required. This can be done using the remove-package client-side tool:
$ ./remove-package -m "reason for removal" konserve
By default this removes the named source and binaries, to remove just a binary use -b:
$ ./remove-package -m "NBS" -b konserve
"NBS" is a common short-hand meaning that the binary is No-longer Built by the Source.
To remove just a source, use -S.
The tool tells you what it's going to do, and asks for confirmation before doing it, so it's reasonably safe to get the wrong options and say N.
If you remove source packages which are in Debian, and they are not meant to ever come back, add it to the blacklist in lp:~ubuntu-archive/+junk/sync-blacklist, document the reason, and bzr commit it with an appropriate changelog. This will avoid getting the package back to source NEW in the next round of autosyncs from Debian.
5.3. Removals in Debian
From time to time we should remove packages which were removed in Debian, to avoid accumulating cruft and unmaintained packages. This client-side tool (from ubuntu-archive-tools) will interactively go through the removals and ask for confirmation:
Please note that we do need to keep some packages which were removed in Debian (e. g. "firefox", since we did not do the "firefox" → "iceweasel" renaming).
5.4. Failed SRUs
If a package should be removed from -proposed, use the remove-package tool (from ubuntu-archive-tools). e.g., to remove source and binaries for the libreoffice package currently in trusty-proposed:
$ ./remove-package -m "SRU abandoned (verification-failed)" -s trusty-proposed libreoffice
Syncing packages with Debian used to be a reasonably common request. It is now self-service for developers using syncpackage. If you are asked to process a sync in the old style, you can use the -s option to syncpackage to do so in the name of the requester.
Most updates available in Debian are automatically synced before DebianImportFreeze, but packages that were previously in Ubuntu will not be automatically reintroduced. To process these interactively:
$ ./auto-sync --new-only
To sync from any source which is not automatically imported by Launchpad, use the syncpackage tool on a .dsc file. Any uploader can do this; it does not require being an archive administrator.
Likewise, backports are now self-service for members of ubuntu-backporters using backportpackage.
Sometimes binary packages are not built by any source (NBS) any more. This usually happens with library SONAME changes, package renamings, etc. Those need to be removed from the archive from time to time, and right before a release, to ensure that the entire archive can be rebuilt by current sources.
Such packages are detected by archive-cruft-check. This tool does not check for reverse dependencies, though, so you should use checkrdepends -b for checking if it is safe to actually remove NBS packages from the archive.
Look at the half-hourly generated NBS report which shows all NBS packages, their reverse dependencies, and a copy-and-paste-able command to clean up the "safe" ones.
The rest needs to be taken care of by developers, by doing transition uploads for library SONAME changes, updating build dependencies, etc. The remaining files will list all the packages which still need the package in question.
Please refrain from removing NBS kernel packages for old ABIs until debian-installer and the seeds have been updated, otherwise daily builds of alternate and server CDs will be made uninstallable.
8. Adjusting Launchpad ACLs
NOTE: due to bug #562451, archive administrators cannot currently adjust Launchpad ACLs.
The new ArchiveReorganisation brings finer grained access controls than what components can provide. Launchpad ACLs allow individuals and teams to have upload or admin rights on certain packages, referred to as sets. In general, an archive administrator can process requests to create and delete package sets, as well as add or remove packages from package sets. Archive administrators should not add individuals or teams to package sets without explicit TechnicalBoard approval.
8.1. Package sets
Packages can be added to or removed from package sets using the edit-acl tool from ubuntu-archive-tools.
To list the packages currently in the package set mozilla:
$ ./edit-acl query -P mozilla -S trusty adblock-plus all-in-one-sidebar bindwood ...
To add a package to the mozilla package set:
$ ./edit-acl -P mozilla -S trusty -s foo -s bar -s baz add
To remove a package from the mozilla package set:
$ ./edit-acl -P mozilla -S trusty -s foo delete
For more information, please see edit-acl --help.
9. Raw UEFI uploads
Launchpad supports autosigning of EFI binaries using the Secure Boot signature format. This is implemented using a "raw uefi" format upload within a binary package build (see the efilinux package in quantal or later for an example). To provide additional assurance that only trusted EFI bootloaders are signed using this method, packages that include raw UEFI binary uploads land in the unapproved queue and require archive admin approval before they are signed. Archive admins should review the corresponding source upload for correctness prior to approving these uploads.
10. Useful tools
There are other useful tools in your PATH which are invaluable.
10.1. Archive state checks
rmadison (in the devscripts package, run on your client system) examines the current state of the archive for a given binary/source package:
$ rmadison dpkg dpkg | 1.10.22ubuntu2 | warty | source, amd64, i386, powerpc dpkg | 1.10.22ubuntu2.1 | warty-security | source, amd64, i386, powerpc dpkg | 1.10.27ubuntu1 | hoary | source, amd64, i386, ia64, powerpc, sparc dpkg | 1.10.27ubuntu1.1 | hoary-security | source, amd64, i386, ia64, powerpc, sparc dpkg | 1.10.27ubuntu2 | hoary-updates | source, amd64, i386, ia64, powerpc, sparc dpkg | 1.13.10ubuntu4 | breezy | source, amd64, hppa, i386, ia64, powerpc, sparc dpkg | 1.13.11ubuntu5 | dapper | source, amd64, hppa, i386, ia64, powerpc, sparc $ rmadison dselect dselect | 1.10.22ubuntu2 | warty | amd64, i386, powerpc dselect | 1.10.22ubuntu2.1 | warty-security | amd64, i386, powerpc dselect | 1.10.27ubuntu1 | hoary | amd64, i386, ia64, powerpc, sparc dselect | 1.10.27ubuntu1.1 | hoary-security | amd64, i386, ia64, powerpc, sparc dselect | 1.10.27ubuntu2 | hoary-updates | amd64, i386, ia64, powerpc, sparc dselect | 1.13.10ubuntu4 | breezy | amd64, hppa, i386, ia64, powerpc, sparc dselect | 1.13.11ubuntu5 | dapper | amd64, hppa, i386, ia64, powerpc, sparc
Or when used with -S and a source package, the source and every binary built by it:
$ rmadison -S dpkg dpkg | 1.10.22ubuntu2 | warty | source, amd64, i386, powerpc dpkg | 1.10.22ubuntu2.1 | warty-security | source, amd64, i386, powerpc dpkg | 1.10.27ubuntu1 | hoary | source, amd64, i386, ia64, powerpc, sparc dpkg | 1.10.27ubuntu1.1 | hoary-security | source, amd64, i386, ia64, powerpc, sparc dpkg | 1.10.27ubuntu2 | hoary-updates | source, amd64, i386, ia64, powerpc, sparc dpkg | 1.13.10ubuntu4 | breezy | source, amd64, hppa, i386, ia64, powerpc, sparc dpkg | 1.13.11ubuntu5 | dapper | source, amd64, hppa, i386, ia64, powerpc, sparc dpkg-dev | 1.10.22ubuntu2 | warty | all dpkg-dev | 1.10.22ubuntu2.1 | warty-security | all dpkg-dev | 1.10.27ubuntu1 | hoary | all dpkg-dev | 1.10.27ubuntu1.1 | hoary-security | all dpkg-dev | 1.10.27ubuntu2 | hoary-updates | all dpkg-dev | 1.13.10ubuntu4 | breezy | all dpkg-dev | 1.13.11ubuntu5 | dapper | all dpkg-doc | 1.10.22ubuntu2 | warty | all dpkg-doc | 1.10.22ubuntu2.1 | warty-security | all dpkg-doc | 1.10.27ubuntu1 | hoary | all dpkg-doc | 1.10.27ubuntu1.1 | hoary-security | all dpkg-doc | 1.10.27ubuntu2 | hoary-updates | all dselect | 1.10.22ubuntu2 | warty | amd64, i386, powerpc dselect | 1.10.22ubuntu2.1 | warty-security | amd64, i386, powerpc dselect | 1.10.27ubuntu1 | hoary | amd64, i386, ia64, powerpc, sparc dselect | 1.10.27ubuntu1.1 | hoary-security | amd64, i386, ia64, powerpc, sparc dselect | 1.10.27ubuntu2 | hoary-updates | amd64, i386, ia64, powerpc, sparc dselect | 1.13.10ubuntu4 | breezy | amd64, hppa, i386, ia64, powerpc, sparc dselect | 1.13.11ubuntu5 | dapper | amd64, hppa, i386, ia64, powerpc, sparc
checkrdepends lists the reverse dependencies of a given binary:
$ checkrdepends -s trusty -b nm-applet
or source package:
$ checkrdepends -s trusty network-manager
10.2. NEW handling
A lot of churn in NEW comes from Debian imports. Since they already went through NEW in Debian, we should not waste too much time on it, so there are some tools.
The first thing you need to handle are native syncs. These are syncs performed via URLs like https://launchpad.net/ubuntu/trusty/+localpackagediffs or via the LP API. You can recognize these in the LP queue pages because they have '(sync)' in the name. In queue info, they show up as 'X-' (as opposed to 'S-' like normal source uploads). There are no changes files for these, so they cannot currently be fetched via queue fetch. To verify a native sync:
Download the source package from Debian (eg, via dget or apt-get source <pkg>=<version>)
Download the imported dsc file from the Debian project in LP (eg https://launchpad.net/debian/sid/+source/pxe-kexec)
- Compare the dsc file from Debian and from LP. Since both should be signed, if they are identical, then you know the package hasn't been tampered with. I can also compare the full source package from Debian and LP if desired.
Once verified, accept it normally via LP or ./queue accept <srcpkg>.
./new-binary-debian-universe accepts all binary NEW packages whose source was imported from Debian and is in universe. With the --lintian option, it runs lintian over all the imported .debs while it runs, so you can watch the output and note all particularly worrisome issues. When you are happy, say yes at each confirmation prompt.
When unpacking a source package for source NEW checks, you should run suspicious-source. This is basically a find -type f which ignores all files with a known-safe name (such as *.c, configure, *.glade). Every file that it outputs should be checked for being the preferred form of modification, as required by the GPL. This makes it easier to spot PDFs and other binary-only files that are not accompanied by a source. The licensecheck command is also useful for verifying the license status of source packages.
10.3. Moving Packages to Updates
Packages in -proposed can be moved to -updates once they are approved by someone from sru-verification, and have passed the minimum aging period of 7 days. Use the sru-release script from ubuntu-archive-tools for this:
$ ./sru-release trusty kdebase
Please see --help, you can also use this tool to copy packages to -security and to the current development release. N.B. before copying a package to -security ping a member of the ubuntu-security team.
10.4. Publishing security uploads from the ubuntu-security private PPA
Security uploads in Soyuz are first built, published, and tested in the Security Team's private PPA. To unembargo them, the security team use a tool that re-publishes them to the primary archive. This is now self-service, although you may occasionally be asked to adjust overrides, which can be done in the usual way.
10.5. Publishing packages from the ubuntu-mozilla-security public PPA
Mozilla (ie, firefox and thunderbird) uploads in Soyuz are first built, published, and tested in the Mozilla Security Team's public PPA. To publish them into the main archive, use copy-package from ubuntu-archive-tools. Note that pocket copies to the security pocket should never be done without an explicit request from a member of the Ubuntu Security Team (Mozilla Security Team is not enough), and copies to the proposed pocket should not be done without an explicit request from a member of the SRU Team. Keep in mind that firefox 2.0 and later (ie hardy and later) will always have a corresponding xulrunner package that needs copying.
To publish firefox version 22.0+build2-0ubuntu0.12.04.2 from the ubuntu-mozilla-security PPA to the -security pocket of ubuntu's precise release, you would do the following:
$ ./copy-package -b --from=~ubuntu-mozilla-security/ubuntu/ppa -s precise --to=ubuntu --to-suite precise-security -e 22.0+build2-0ubuntu0.12.04.2 firefox
Alternatively, can use lp:ubuntu-qa-tools/security-tools/unembargo like so:
$ unembargo --ppa=ubuntu-mozilla-security -r trusty --pocket=proposed chromium-browser
10.6. Publishing packages from the ubuntu-security-proposed public PPA to proposed
This works the same as the ubuntu-mozilla-security PPA, above. Eg, using lp:ubuntu-qa-tools/security-tools/unembargo:
$ unembargo --ppa=ubuntu-security-proposed -r trusty --pocket=proposed gnupg
10.7. Copying PPA kernels to proposed
The two most useful URLs for this process are the Kernel SRU Report, where you will find links to the tracking bugs (the magnifying glasses), as well as the status of each package in each release, and the Kernel SRU workflow, which outlines in fine detail how each bug task should be handled, what the states mean, etc. The executive summary of the previous link is "only operate on tasks assigned to your team, and only when they're in the Comfirmed state, and when you do, please reassign to yourself and set the task to Fix Released when you're done".
The Pending SRU report has a section for the kernel PPA which shows all newer kernels in the PPA, provides clickable links to open all bugs (with separate CVE bugs), and copy&pasteable copy-proposed-kernel and sru-accept commands (both in ubuntu-archive-tools). To publish linux version 2.6.32-27.49 from the canonical-kernel-team PPA to the -proposed pocket of ubuntu's lucid release, you would do the following:
Click on the "open bugs" button and check that the bugs are in a reasonable state, i. e. they target the right source package (linux vs. linux-ec2 etc.), are fixed in the development release (or at least upstream), and that the changes are limited to bug fixes, and are in general within the boundaries of the StableReleaseUpdates policy. They should ideally have a task for the stable release the SRU targets. Note that this button does not open CVE bugs, as they don't get verification or other tracking (there is a separate button for opening them, if desired).
- Find the tracking bug by either traversing through the list of bugs, or opening the .changes file and looking at the top (the release bug is pointed out there). Ensure that there is a proper stable task, and that the main (development release) task is invalid.
Run the copy-proposed-kernel command to copy it to -proposed. Once the kernels are copied to proposed and accepted, update the bug to close the Promote-to-proposed task and assign it to yourself.
However, with some flavours like -ec2 or armel kernels, which are mostly just a merge with the main linux kernel, it is too much overhead to add -ec2 tasks to all the bugs.
Due to current limitations of Launchpad, new packages copied from a PPA into the archive sometimes go to 'universe'. As a result, please verify the overrides for all packages copied to -proposed, otherwise these packages might become uninstallable when they are ultimately copied to -updates/-security. find-bin-overrides from lp:ubuntu-qa-tools can help with this. You use it like so: find-bin-overrides <pocket to compare to> <target pocket> <ubuntu release> <source package>=<version in pocket to compare to>,<old abi>,<new abi>. Eg, suppose there is a new kernel in hardy-proposed with a new ABI of 2.6.24-30 and you want to get a list of overrides for the new kernel based on the old ABI of 2.6.24-16 in the 22.214.171.124-16.34 version from the release pocket of hardy. For the linux-restricted-modules-2.6.24 source package, you might use:
$ find-bin-overrides release proposed hardy \ linux-restricted-modules-2.6.24=126.96.36.199-16.34,2.6.24-16,2.6.24-30 # hardy/linux-restricted-modules-2.6.24 ./change-override -c multiverse -s hardy-proposed fglrx-kernel-source ... ./change-override -c restricted -s hardy-proposed avm-fritz-firmware-2.6.24-30 ...
For the linux source package, you might use:
$ find-bin-overrides release proposed hardy linux=2.6.24-16.30,2.6.24-16,2.6.24-30 # hardy/linux ...
You may also specify --show-main to also show the the change-override command to move things to main. This can be useful if you know the overrides are very wrong. See find-bin-overrides -h for details.
TODO: A process/script similar to kernel-overrides should be developed to make sure overrides are properly handled for binaries not in main. Is find-bin-overrides from lp:ubuntu-qa-tools good enough?
10.8. Copying security uploads to updates
Security uploads are distributed from a single system, security.ubuntu.com (consisting of one or a small number of machines in the Canonical datacentre). While this ensures much quicker distribution of security updates than is possible from a mirror network, it places a very high load on the machines serving security.ubuntu.com, as well as inflating Canonical's bandwidth expenses very substantially. Every new installation of a stable release of Ubuntu is likely to be shortly followed by downloading all security updates to date, which is a significant ongoing cost.
To mitigate this, we periodically copy security uploads to the -updates pocket, which is distributed via the regular mirror network. (In fact, the pooled packages associated with -security are mirrored too, but mirrored -security entries are not in the default /etc/apt/sources.list to avoid causing even more HTTP requests on every apt-get update.) This is a cheap operation, and has no effect on the timely distribution of security updates, other than to reduce the load on central systems.
The copy-report tool lists all security uploads that need to be copied to -updates. If the package in question is not already in -updates, it can be copied without further checks. Otherwise, copy-report will extract the changelogs (which may take a little while) and confirm that the package in -security is a descendant of the package in -updates. If that is not the case, it will report that the package needs to be merged by hand.
The output of the tool looks like this:
$ ./copy-report The following packages can be copied safely: -------------------------------------------- copy-package -y -b -s feisty-security --to-suite feisty-updates -e 8.3.5-6ubuntu2.1 tk8.3 copy-package -y -b -s feisty-security --to-suite feisty-updates -e 8.4.14-0ubuntu2.1 tk8.4
The block of output under "The following packages can be copied safely:" may be copied and pasted in its entirety (or run copy-report --safe). If there is a block headed "The following packages need to be merged by hand:", then make sure that the security team is aware of those cases.
Note that copy-report --safe is run from a cron job as the ubuntu-archive user on people.canonical.com, and so does not typically need to be run by hand.
10.9. Other copies
copy-package is a versatile tool and can be used for a number of other purposes. If you are doing something not documented here, please ask on #ubuntu-release first.
Archive administrators technically (as in, per the ACLs) have the ability to copy into the RELEASE pocket of the current development series. Please do not do this; that pocket is owned by the proposed-migration tools, and those tools have built-in override facilities for the cases where they are wrong. The release team has access to apply such overrides when needed.
10.10. Handling updates to partner
Updates to the partner archive follow a similar process as packages in the Ubuntu archive. Specifically, packages are first built in the proposed pocket, then they need to be copied to the release pocket after they are built and then cleaned up from the proposed pocket. The process is (examples show adobe-flashplugin being updated for trusty):
- Review the package in the "unapproved" queue, and if appropriate, accept the package into partner for the proposed pocket (in this example, proposed for trusty)
- When the package builds on all architectures, copy it to the partner release pocket (this makes it available to users). Eg:
$ ./copy-package -b --auto-approve --from=ubuntu/partner -s trusty-proposed --to-suite trusty adobe-flashplugin
or to do all at once:
$ for i in precise trusty xenial ; do ./copy-package -b --auto-approve --from=ubuntu/partner -s $i-proposed --to-suite $i adobe-flashplugin ; done
- Remove the package from proposed in the partner archive. Eg:
$ ./remove-package -A ubuntu/partner -m "copied to release" -s trusty-proposed adobe-flashplugin
or to do all at once:
$ for i in precise trusty xenial ; do ./remove-package -A ubuntu/partner -m "copied to release" -s $i-proposed adobe-flashplugin ; done
10.11. Diffs for unapproved uploads
The "unapproved" queue holds packages while a release is frozen, i. e. while a milestone or final freeze is in progress, or for post-release updates (like hardy-proposed). Packages in these queues need to be scrutinized before they get accepted.
This can be done with the queuediff tool in ubuntu-archive-tools, which generates a debdiff between the current version in the archive, and the package sitting in the unapproved queue:
$ ./queuediff -s hardy-updates hal $ ./queuediff -b human-icon-theme | view -
-s specifies the release pocket to compare against and defaults to the current development release. Please note that the pocket of the unapproved queue is not checked or regarded; i. e. if there is a hal package waiting in hardy-proposed/unapproved, but the previous version already migrated to hardy-updates, then you need to compare against hardy-updates, not -proposed.
Check --help, the tool has more options, such as specifying a different mirror, or -b to open the referred Launchpad bugs in the webbrowser.
This tool works very fast if the new package does not change the orig.tar.gz, then it only downloads the diff.gz. For native packages or new upstream versions it needs to download both tarballs and run debdiff on them. Thus for large packages you might want to do this manually in the data center.
11. Useful runes
This section contains some copy&paste shell bits which ease recurring jobs.
In some cases, binary packages fail to move from the incoming queue to the accepted queue. To fix this, run ~lp_buildd/reprocess-failed-to-move as lp_buildd
11.2. Reprocessing failed source uploads
If a source upload fails for spurious/transient reasons (you can check in pepo:/srv/launchpad.net/production-logs/lp_queue/process-upload.log), ask webops to locate the appropriate upload-* directory and corresponding .distro file in /srv/launchpad.net/ubuntu-queue/ (they will probably be in either failed or rejected) and move them both back to /srv/launchpad.net/ubuntu-queue/incoming/.
12. Stable release updates
SRU packages in -proposed must be approved by ~ubuntu-sru before accepting.
12.1. langpack SRUs
Language packs are a special case; these packages are normally uploaded as a batch and will not normally reference specific bugs. The status page will only show language-pack-en. Please see the documentation how to copy packages between PPA, -proposed, and -updates.
13. Other archives
14. Useful web pages
Equally useful to the tools are the various auto-generated web pages in ubuntu-archive's public_html that can give you a feel for the state of the archive.
- As described above, this lists the differences between the archive and the output of the germinate script. Shows up packages that are in the wrong place, or need seeding.
- This is the output of the germinate script, split up into each release of each flavour of ubuntu.
- Shows discrepancies between priorities of packages and where they probably should go according to the seeds.
- Shows override discrepancies between architectures, which are generally bugs.
Generated by the half-hourly run of britney and indicates packages that are uninstallable on trusty, usually due to missing dependencies or problematic conflicts.
- Lists differences between binary and source versions in the archive. This often shows up both build failures (where binaries are out of date for particular architectures) but also where a binary is no longer built from the source.
This contains a list of binary packages which are not built from source (NBS) any more. The files contain the list of reverse dependencies of those packages (output of checkrdepends -b). These packages need to be removed eventually, thus all reverse dependencies need to be fixed. This is updated half-hourly.
15. Chroot management
Please note that chroot management is something generally handled by Canonical IS (and specifically by Adam Conrad). The following section documents the procedures required should one have to, for instance, remove all the chroots for a certain suite to stop the build queue in its tracks while a breakage is hunted down and fixed, but please don't take this as an open invitation to mess with the buildd chroots willy-nilly.
Soyuz stores one chroot per (suite, architecture).
manage-chroot allows the following actions upon a specified chroot:
$ ./manage-chroot Usage: manage-chroot -a ARCHITECTURE [options] <get|info|remove|set> manage-chroot: error: You must specify an architecture.
Downloading (get) an existing chroot:
$ ./manage-chroot [-s SUITE] <-a ARCH> get
The chroot will be downloaded and stored in the local disk name as 'chroot-<DISTRIBUTION>-<SERIES>-<ARCHTAG>.tar.bz2'
Uploading (add/update) a new chroot:
$ ./manage-chroot [-s SUITE] <-a ARCH> set -f <CHROOT_FILE>
The new chroot will be immediately used for the next build job in the corresponding architecture.
Disabling (remove) an existing chroot:
Unless you have plans for creating a new chroots from scratch, it's better to download them to disk before the removal (recover is possible, but involves direct DB access)
$ ./manage-chroot [-s SUITE] <-a ARCH> remove
No builds will be dispatched for architectures with no chroot, the build-farm will continue functional for the rest of the system.
16. Archive days
This is currently being re-assessed to a more task oriented approach, rather than regular admin days.
Current members with regular admin days are:
Available for adhoc requests:
On an archive day, the following things should be done:
Process all pending archive bugs. Most of those are syncs, removals, component fixes, but there might be other, less common, requests.
Process the NEW queues of the current development release and *-backports of all supported stable releases.
If we are not yet in the DebianImportFreeze, run process-removals to review/remove packages which were removed in Debian.
- Clean up component-mismatches, and poke people to fix dependencies/write MIRs.
Look at http://people.canonical.com/~ubuntu-archive/testing/trusty_probs.html, fix archive-admin related issues (component mismatches, etc.), and prod maintainers to fix package related problems.
- Remove NBS packages without reverse dependencies, and prod maintainers to rebuild/fix packages to eliminate reverse dependencies to NBS packages.
16.1. Archive Administration and Freezes
Archive admins should be familiar with the FreezeExceptionProcess, however it is the bug submitter's and sponsor's responsibility to make sure that the process is being followed. Some things to keep in mind for common tasks:
- When the archive is frozen (ie the week before a Milestone, or from one week before RC until the final release), you need an ACK from ubuntu-release for all main/restricted uploads
During the week before final release, you need an ACK from ubuntu-release for any uploads to universe/multiverse
When the archive is not frozen, bugfix-only sync requests can be processed if filed by a core-dev, ubuntu-dev or motu (universe/multiverse only) or have an ACK by a sponsor or someone from ubuntu-sponsors.
After FeatureFreeze, all (new or otherwise) packages in the archive (ie main, restricted, universe and multiverse) require an ACK from ubuntu-release for any FreezeException (eg FeatureFreeze, UserInterfaceFreeze, and Milestone). Packages that do not require a FreezeException can be processed normally.
See FreezeExceptionProcess for complete details.
