Comment 1 for bug 1781586

This bug was fixed in the package unattended-upgrades - 1.4ubuntu2

---------------
unattended-upgrades (1.4ubuntu2) cosmic; urgency=medium

  * Redirect stderr output in upgrade-all-security and
    upgrade-between-snapshots otherwise it breaks the test (LP: #1781446)
  * Skip rebuilding python-apt in upgrade autopkgtests.
    Python-apt has a new build dependency making the rebuilding as is failing
    and the reference handling issue is worked around in unattended-upgrades
    already, install release's latest python-apt in upgrade-all-security
    instead (LP: #1781586)
