[Python-modules-team] Bug#1001429: python-qtpy: (autopkgtest) needs update for python3.10: deprecation warning on stderr

[Paul Gevers]

Version: 1.9.0-3
Severity: serious

Dear maintainer(s),

We are in the transition of adding python3.10 to the supported Python 
versions [0]. With a recent upload of python3-defaults the autopkgtest 
of python-qtpy fails in testing when that autopkgtest is run with the 
binary packages of python3-defaults from unstable. It passes when run 
with only packages from testing. In tabular form:

                        pass            fail
python3-defaults       from testing    3.9.8-1
python-qtpy            from testing    1.9.0-3
all others             from testing    from testing

I copied some of the output at the bottom of this report. As the test 
passes otherwise, either suppress deprecation warnings, fix the issue 
and/or use the allow-stderr restriction in autopkgtest to avoid having 
autopkgtest fail on warnings.

Currently this regression is blocking the migration of python3-defaults 
to testing [1]. https://docs.python.org/3/whatsnew/3.10.html lists 
what's new in Python3.10, it may help to identify what needs to be updated.

Testing with python3.10:
/usr/lib/python3/dist-packages/qtpy/__init__.py:65: DeprecationWarning: 
The distutils package is deprecated and slated for removal in Python 
3.12. Use setuptools or check PEP 632 for potential alternatives
   from distutils.version import LooseVersion
