 1. Propose

  All proposals for stable release updates must be '''approved''' by members of the [https://launchpad.net/people/motu-sru MOTU Stable Release Updates team]. A convenient way to do this is to attach all of the information to the bug report, then subscribe the `motu-sru` team. SRU proposals must be accompanied by the following information for each bug to be addressed:

   * A '''bug number''' referring to a complete bug report describing the problem and its effect
   * A '''statement explaining the impact''' of the bug on users and justification for backporting the fix to the stable release
   * An explanation of '''how the bug has been addressed''' in the development branch, including the relevant version numbers of packages modified in order to implement the fix
   * A '''patch''' applicable to the stable version of the package. If preparing a patch is likely to be time-consuming, it may be preferable to discuss the first three items before preparing a patch.

  A copy of this proposal and a hyperlink to any prior discussion thread should be added to the bug report as a comment, usually by CCing ''bugnumber''`@bugs.launchpad.net`.

Universe SRU Policy

Once an Ubuntu release has been completed and published, updates for it are only released under certain circumstances, and must follow a special procedure.

Why

In contrast to pre-release versions, official releases of Ubuntu are subject to much wider use, and by a different demographic of user. During development, changes to the distribution primarily affect developers, early adopters and other advanced users, all of whom have elected to use pre-release software at their own risk.

Users of the official release, in contrast, expect a high degree of stability. They use their Ubuntu system for their day-to-day work, and problems they experience with it can be extremely disruptive. Many of them are less experienced with Ubuntu and with Linux, and expect a reliable system which does not require their intervention.

Stable release updates are automatically recommended to a very large number of users, and so it is critically important to treat them with great caution. Therefore, when updates are proposed, they must be accompanied by a strong rationale and present a low risk of regressions.

For packages in the Universe and Multiverse components, whilst they are popular, they are not installed by default and therefore have a lower risk of affecting many users if a regression occurs.

When

Stable release updates will, in general, only be issued in order to fix high-impact bugs. Examples of such bugs include:

  • Bugs which may, under realistic circumstances, directly cause a security vulnerability

  • Bugs which represent severe regressions from the previous release of Ubuntu

  • Bugs which may, under realistic circumstances, directly cause a loss of user data

How

This process is to be followed for all updates except those to fix security updates, which are only released by the Ubuntu security team. Security procedures are documented at SecurityUpdateProcedures.

  1. Prepare
    • Once an update has been agreed on and falls under the criteria above, an upload can be prepared. The following criteria apply to any packages modified as part of the update:

      • The changelog entry and resulting .changes file must include a reference to the corresponding bug report(s)

      • The version number(s) must be carefully checked in order to avoid clashing with any other version of the package, past, present or future. A general "best practice" is to use the suffix ~proposed1 or ~prop1.

      • The upload target must be release-proposed

      Once the upload is ready, attach a complete source package diff (debdiff) to the bug report for review. The sponsor of the upload is responsible for testing the update.

  2. Upload

    • After the upload, archive administrators should then verify that the version number of the upload is sane and accept the package into -proposed. They set the bug status to Fix committed.

  3. Test

    • Once the update has been published in -proposed, it can be tested by a wider audience.

    • Notify the MOTU team via the ubuntu-motu mailing list [mailto:ubuntu-motu@lists.ubuntu.com <ubuntu-motu@lists.ubuntu.com>] of the availability of this package for testing

      • Prepend "StableReleaseUpdates" to the Subject line of your e-mail.

      • Add a verification-motu-needed tag to the bug report.

    • Test the package yourself

    • If the testing period is over and there 2 persons have stated "works for me", motu-sru will set the tag verification-motu-done.

  4. Release

    • After at least 2 persons have tested the package and attached a "works for me" comment to the bug and after a minimum aging period of 7 days, motu-sru will prepare a second upload to release-updates:

    • Include a changelog entry with:
      • A new version number (the same cautions apply regarding the choice of version number)

      • Confirmation of the above testing, including the name of the tester in each case

    • Make no other changes relative to the version in -proposed

      The archive administrators must verify that uploads to -updates meet these criteria. In the future, the update from -proposed will be copied verbatim instead, once the necessary infrastructure is available.

  5. Following up

    • Add yourself as a bug contact for the package in Launchpad, if you are not one already

    • For 7 days after the update is released, monitor Launchpad for bug reports relating to the update

    • In the event of a regression, immediately notify the [mailto:ubuntu-motu@lists.ubuntu.com Ubuntu Universe maintainers] via email, and ask for help on #ubuntu-motu.
