Comment 1 for bug 1803399

Fixed in launchpadlib 1.10.8:

1.10.8 (2019-11-26)
===================
- Squash a deprecation warning on Python >= 3.7 in
  launchpadlib.testing.launchpad.
- Switch from buildout to tox.
- Weaken hosted-files test slightly to avoid problems with zope.publisher >=
  4.2.2.
