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

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Benjamin Drung (bdrung):

"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]:   File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2679, in parsed_version
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]:     raise InvalidVersion(f"Invalid version: '{version}'")
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.

There is a main ticket for fixing those non-PEP-440 packages: bug
#1991606
