[Bug 2060721] Re: APT 2.8.0: Promote weak key warnings to errors

[Steve Langasek]

Hello Julian, or anyone else affected,

Accepted apt into noble-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/apt/2.8.0 in a few
hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
noble to verification-done-noble. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-noble. In either case, without details of your testing we will
not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

** Changed in: apt (Ubuntu Noble)
       Status: Incomplete => Fix Committed

** Tags added: verification-needed verification-needed-noble

Title:
  APT 2.8.0: Promote weak key warnings to errors

Status in apt package in Ubuntu:
  Incomplete
Status in apt source package in Noble:
  Fix Committed

Bug description:
  ⚠️ Only land this in the release/updates pocket after PPAs have been
  resigned

  (This bumps the apt version to 2.8.0. APT uses the odd/even number
  system, with 2.7.x being the development series for 2.8, and this is
  the only change left for the 2.8 release, safe for some minor
  translation/test suite improvements)

  (This will be uploaded after the beta and may be released before noble
  release, as a zero day SRU or within the weeks following the release)

  [Impact]
  APT is currently just warning about keys that it should be rejecting to give Launchpad time to resign PPAs. This needs to be bumped to an error such that the crypto policy is fully implemented and we only trust keys that are still being trusted. #2055193

  A warning provides some help right now to third-parties to fix their
  repositories, but it's not *safe*: A repository could have multiple
  signing keys and be signed by a good key now, then later, a previous
  key still in trusted.gpg.d could be revoked and we'd degrade to
  warnings, which, given that we update in the background automatically,
  the user may not see.

  Other fixes:
  - The test suite has been made less flaky in two places
  - Documentation translation has been unfuzzied for URL changes in 2.7.14

  [Test plan]
  The vast regression test suite prevents regression in other components. Additional tests are:

  1. (promotion to error) Take a repository that has a weak key warning, upgrade apt and check that it is an error
  2. (still valid) Check that the main Ubuntu repositories and/or resigned PPAs work correctly.

  We don't have any tests for the test changes or the documentation
  translation URL unfuzzying.

  [Where problems could occur]
  apt will start to fail updates of repositories with weak signing keys, but it will have warned users about that before. Given that it is still early in the cycle, and we only enable updates for 24.04.1, this seems the right tradeoff for future security.
