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

[Brian Murray]

Using the version of the dist-upgrader from focal-proposed I did not
encounter a Traceback and did end up with a crash file about the
installation of pure-ftpd-common. So I'm setting this to verification-
done.

bdmurray at clean-bionic-amd64:/tmp/u-r-u$ ls /var/crash/
pure-ftpd-common.0.crash
bdmurray at clean-bionic-amd64:/tmp/u-r-u$ head /var/log/dist-upgrade/main.log

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.
