[Bug 2104284] Re: tzdata 2025b release

[Andreas Hasenack]

The jammy upload is also adding the new DEP8 test, but disabled:

Looking at the mentioned bug, it's "fix released" for jammy. Is this
disabling still necessary?

If yes, it doesn't qualify for a test plan for jammy.

Bug description:
  [ Impact ]

  The 2025b release contains the following changes:

  * New America/Coyhaique zone for Aysén Region in Chile, which moves
    from -04/-03 to -03. It will not change its clocks on 2025-04-05.
  * Improve historical data for Iran

  [ Test Plan ]

  Test cases were added to the autopkgtest to cover the testing:

  * python: test_2025b

  So the test plan is to check that the autopkgtest succeeds. Since
  https://launchpad.net/bugs/207604 hasn't been backported to focal, we
  need to test focal manually:

  * dpkg-reconfigure tzdata
  * Select America/Coyhaique
  * This zone should be available

  [ Other Info ]

  * The autopkgtest for chrony is flaky on jammy and newer (see bug #2002910).
  * The oracular autopkgtest for exchange-calendars needs to use 4.5.5-2ubuntu0.1
  * The focal autopkgtest for postgresql-12 needs to use 12.22-0ubuntu0.20.04.3
