[Python-apps-team] Bug#953966: buildbot: autopkgtest failure with Python 3.8 as default

Source: buildbot
Version: 2.6.0-1

Hi Maintainer

The autopkgtests of buildbot started to fail with Python 3.8 as the
default Python3 interpreter [1].

I've copied what I hope is the relevant part of the log below.
