[Python-apps-team] Bug#954451: src:tox: Please remove python2 autopkgtests that use virtualenv

[Scott Kitterman]

Package: src:tox
Version: 3.13.2-1
Severity: serious
Tags: ftbfs
Justification: fails to build from source (but built successfully in the past)

Note: Using FTBFS to cover autopkgtest failure as it is a rough
equivalent (package can't migrate to testing).

The python-virtualenv package can no longer support creation of python2
virtualenvs without external downloads, which are not allowed for
packages in Main.  The ipaddr module is no longer in Testing and is
required for this.  As a result, tox python2 autopkgtests now fail:

py2 create: /tmp/autopkgtest-lxc.zhf4r5q1/downtmp/autopkgtest_tmp/.tox/py2
ERROR: invocation failed (exit code 1), logfile: /tmp/autopkgtest-lxc.zhf4r5q1/downtmp/autopkgtest_tmp/.tox/py2/log/py2-1.log

I'm happy to do an NMU to simply drop the tests if you would like.
Please let me know if you plan to take care of it.  I will probably NMU
in a week (including the NMU diff in this bug once I have it ready) if I
don't.

Thanks,
