[Bug 1821640] Re: Missing pattern for linux-image-unsigned keeps autoremovable kernels on the system

[Łukasz Zemczak]

Hello Balint, or anyone else affected,

Accepted apt into disco-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/apt/1.8.1 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 and change the tag from
verification-needed-disco to verification-done-disco. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-disco. 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.

Bug description:
  [Impact]
  Unattended-upgrades keeps versioned kernel packages because they don't match known kernel package patterns:

  ...
  Keeping auto-removable linux-modules-4.18.0-14-generic package(s) because it would also remove the following packages which should be kept in this step: linux-image-unsigned-4.18.0-14-generic
  ...

  For reproduction see LP: #1795696, but running u-u with --verbose.

  And APT does not apply proper kernel-version based protection to it.

  [Test case]
  linux-image-unsigned should popup in the same list in 01autoremove-kernels as linux-signed-image, and should be autoremovable iff it's signed counterpart is autoremovable.

  [Regression potential]
  Not really any, it's just an additional string in the entry. The only difference really possible therefore is that the set of autoremovable packages changes and unattended-upgrades and friends might autoremove different sets of them.
