[Bug 2008430] Re: Aptdaemon crashes when there are any non-PEP-440 packages on the system due to setuptools 66.x.x

[Eugene Crosser]

@amberella-777 that is probably because you do not have any python
packages whose version pkg_resources considers "invalid".  In my case,
it currently stumbles on `syncthing` package (from a third party repo)

In my view, it is unrealistic to expect that _all_ python packages
installed on a system from different sources will become pep-404
compliant in the near future. And it takes just _one_ non-compliant
python package, that may not even come from an apt repo, to break
aptdaemon.

Title:
  Aptdaemon crashes when there are any non-PEP-440 packages on the
  system due to setuptools 66.x.x

Status in aptdaemon package in Ubuntu:
  Confirmed

Bug description:
  "Software Updater" stopped working, it shows message "You stopped the
  check for updates".

  update-manager.desktop[22442]: dbus.exceptions.DBusException:
  org.freedesktop.DBus.Error.NoReply: Message recipient disconnected
  from message bus without replying

  Analysis shows that this is the result of aptdaemon crash when it
  tries to load plugins, and pkg_resources module refuses to parse non
  PEP-440 compliant Python package versions. There are many such python
  packages, one of them "devscripts", as shown in this log, but if I
  remove devscripts, it crashes on other packages.

  org.debian.apt[22501]:     self._parsed_version = parse_version(self.version)
  org.debian.apt[22501]:                            ^^^^^^^^^^^^^^^^^^^^^^^^^^^
  org.debian.apt[22501]:   File "/usr/lib/python3/dist-packages/pkg_resources/_vendor/packaging/version.py", line 266, in __init__

  org.debian.apt[22501]: pkg_resources.extern.packaging.version.InvalidVersion: Invalid version: '2.22.2ubuntu5'
  org.debian.apt[22501]: (package: devscripts)

  There is an upstream ticket against setuptools:
  https://github.com/pypa/setuptools/issues/3772

  It looks like either setuptools has to be fixed or downgraded, or
  aptdaemon modified to not use pkg_resources module.
