[Bug 1884148] Re: dist upgrade process passes a number along with package to apport

[Brian Murray]

Hello errors.ubuntu.com, or anyone else affected,

Accepted ubuntu-release-upgrader into focal-proposed. The package will
build now and be available at https://launchpad.net/ubuntu/+source
/ubuntu-release-upgrader/1:20.04.21 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-
focal to verification-done-focal. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-focal. 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.

Title:
  dist upgrade process passes a number along with package to apport

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Focal:
  Fix Committed

Bug description:
  [Impact]
  The distribution upgrade process is passing to apport packages with numbers prepended to them, this then causes apport to crash and bugs about package installation failures not to be reported.

  [Test Case]
  1) Install the package pure-ftpd on an 18.04 LTS system
  2) Run 'do-release-upgrade -d' to upgrade to 20.04 LTS

  With the version of the dist-upgrader in the release pocket you'll
  receive the Traceback in comment #2.

  To test the dist-upgrader from -proposed you'll actually have to
  download and use the dist-upgrader tarball from
  http://archive.ubuntu.com/ubuntu/dists/focal-proposed/main/dist-
  upgrader-all/current/focal.tar.gz. When running that version of the
  dist-upgrader you should not receive a Traceback and have a pure-ftpd-
  common crash file in /var/crash/.

  This is actually also recreatable when upgrading from 19.10 to 20.04
  and that would be easier as you can use 'do-release-upgrader -p' to
  test the new version of the dist-upgrader.

  [Regression Potential]
  The code change is a just a simple check to see if the package name starts with a number which then removes the number. So the only chance of regression is the additional python code being bad which it isn't.
