Bug Description

[ Impact ]
python-libmaas is not currently usable in any release where the Python version is >= 3.10.

[ Test Plan ]

Standalone tests:

sudo apt install python3-libmaas
python3 -c "import maas.client"

Error:

Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/lib/python3/dist-packages/maas/client/__init__.py", line 8, in <module>
    from .utils.maas_async import asynchronous
  File "/usr/lib/python3/dist-packages/maas/client/utils/__init__.py", line 29, in <module>
    from collections import (
ImportError: cannot import name 'Iterable' from 'collections'
(/usr/lib/python3.11/collections/__init__.py)

This also impact the use of the libmaas API from the hacluster charm - this will be used to validate the updates as well by following the deployment guide for masakari:

https://docs.openstack.org/charm-guide/latest/admin/instance-ha.html

[ Where problems could occur ]

The proposed resolution for this issue is to update to the latest patch release for libmaas - this brings the potential for other regressions however the package is completely unusable in its current form and 0.6.8 is the current recommended version from the MAAS project (and is used via PPA by most users).

The proposed update will also enable test execution as part of the package
build to reduce the risk of a breaking change.

[ Other Info ]

The latest libmaas release is 0.6.8 - the changelog between 0.6.4 and 0.6.8 is mainly bug fixes and enablement of snaps:

[ Original Bug Report ]
The python3-libmaas package in Ubuntu 22.04 does not work:

It looks like upstream has fixed several Python 3.10 compatibility issues in the master branch recently:
