[Python-modules-team] Bug#998473: unittest2: not compatible with Python 3.10

Source: unittest2
Version: 1.1.0-7
Severity: important

Hi Maintainer

unittest2 1.1.0 is not compatible with Python 3.10 because it uses
collections.MutableMapping, which has been removed [1].

I'm filing this bug with severity important, but it will be upgraded
to serious once python3.10 becomes a supported version in debian,
since it will cause several packages to FTBFS.

Regards
Graham
