Before requesting a sync

Syncs (like uploads) cannot be reversed or undone. ALWAYS thoroughly check a package before asking for a sync. In particular, if there are Ubuntu changes in the current package, you must ensure the Ubuntu changes have been merged or are no longer relevant. If the Ubuntu changes are still relevant, the package should be merged from Debian, not synced.

Sometimes the sponsor requires a build log of the Debian package compiled in the Ubuntu release as proof that the new Debian version still compiles in Ubuntu. The build log has to be attached to the sync request.

After FeatureFreeze, syncs of a newer upstream version require a freeze exception.

You should always sync a package rather than uploading the unmodified source by hand, as it is safer and more accurate. If you know you will upload modified source immediately, modify the package and make an -<n>ubuntu<n> upload rather than requesting a sync. However, be sure to always use the exact same .orig.tar.gz as Debian (or whomever).

After DebianImportFreeze, it's a good idea to review the Debian changes to make sure that the fixes will improve Ubuntu: some changes (maintainer change, new uploader, NMU acknowledgement with no additional fixes, etc.) may be better left for the next cycle.

If the version in Ubuntu is a -0ubuntu* version, i.e. it introduces a new upstream that Debian doesn't have it is important to check that the md5sum of the .orig.tar.gz in the Ubuntu archive matches the md5sum of the tarball in the Debian archive (or wherever the sync is from). If it does not match then you risk problems where the source package cannot be unpacked, or where it is not even valid in the first place. If it does not match then you will have to do a fakesync.

For people requiring sponsorship

Content of a sync request

When requesting a 'sync', please include the following information:

  • Information to put into the Summary:
    • Source package name
    • Source package version number to sync
    • Where to sync from (e.g. 'Debian sid main', 'Debian experimental non-free')
  • Information to put into the Bug Description:
    • If there are Ubuntu changes apart from debian/changelog or if FeatureFreeze is in effect:

      • A copy of the entries from debian/changelog corresponding to the changes relative to the current version in Ubuntu
    • If there are Ubuntu changes:
      • a description of each of the Ubuntu changes (a bullet point list is fine, but copies of debian/changelog aren't)
      • a brief explanation of why each one may be dropped (e.g., it's been merged into Debian, is no longer appropriate, etc.)
      • an explicit confirmation that the Ubuntu changes should be overridden

To request a sync, file a bug in Launchpad with the above information (the requestsync tool discussed below makes this simple). Once the bug is complete and correct, subscribe (NOT assign) ubuntu-sponsors. They will review the request and perform the sync for you using the syncpackage tool. (Previously syncs went through the Archive Administrators. This process is now deprecated.)
