ansible-lint crashes in 24.04

[Alexander Sitnik]

Running ansible-lint in Ubuntu 24.04 on my role ends up with a stack trace:

Traceback (most recent call last):
  File "/usr/bin/ansible-lint", line 5, in <module>
    from ansiblelint.__main__ import _run_cli_entrypoint

               ^^^^^^^^^^^^^^^^^^^^^^
AttributeError: module 'pathlib' has no attribute '_posix_flavour'

This is due to python3-wcmatch=8.4-2 being incompatible with python3.12. Upstream fixed this in the next version https://github.com/facelessuser/wcmatch/releases/tag/8.5

I think the following portion of changes can be added to library package for Noble release:
https://github.com/facelessuser/wcmatch/pull/203/files#diff-081b2096c270ab6b17a6c70f95ea07d24dd0d343522e135dbdeb609e59867186L83

[Matthias Lüscher (m-luescher)]

The Python compatibility is actually fixed in the upstream wcmatch package:
https://github.com/facelessuser/wcmatch/releases/tag/8.5

(Update: Sorry - I did not see that this already got reported.)

[Alexander Sitnik (alex-sitnik)]

Matthias, yes I know. I've mentioned this in bug report.

Is there any chance that newer version of python3-wcmatch will reach Noble release?

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Sorin Sbarnea (ssbarnea)]

We are going to add https://github.com/ansible/ansible-lint/pull/4130 upstream to prevent accidental installation of incompatible dependencies. Feel free to switch to the newer version to avoid this issue.

Note that linter switched to CalVer, so don't be scared about the major version change (is not really breaking one).

There are no plans for backporting as we currently support only latest version (no maintenance branches).

[Sorin Sbarnea (ssbarnea)]

Basically the correct description for this bug is: "ubuntu 22.04 ships a broken python3-wcmatch" because it is known that the version shipped is incompatible with python 3.12, which happens to be the system python.

Once wcmatch is update to 8.5.0 or newer the linter will start working.
