[Python-modules-team] Bug#981766: autopkg tests failing with setuptools 52.0

[Matthias Klose]

Control: severity -1 serious

the sources read:

$ fgrep -r pytest .
./.travis.yml:    # disabled because nosetests is not supported on 3.9. We'll
move to pytest.

and indeed running the tests with nose fails.  It looks like the 1.3.0 version
has proper support for pytest.
