[Debian-ha-maintainers] Bug#1009092: crmsh: (autopkgtest) needs update for python3.10: module 'collections' has no attribute 'MutableSet'

[Paul Gevers]

Source: crmsh
Version: 4.3.1-1
Severity: serious
Tags: sid bookworm
User: debian-ci at lists.debian.org

Usertags: python3.10
Control: affects -1 src:python3-defaults

Dear maintainer(s),

We are in the transition of making python3.10 the default Python 
versions [0]. With a recent upload of python3-defaults the autopkgtest 
of crmsh 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    3.10.4-1
crmsh                  from testing    4.3.1-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

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. https://docs.python.org/3.9/library/collections.html says:
"""
Deprecated since version 3.3, will be removed in version 3.10: Moved 
Collections Abstract Base Classes to the collections.abc module. For 
backwards compatibility, they continue to be visible in this module 
through Python 3.9.
"""
Time to move on.
