Regarding the failing autopkgtest:

* python-tz on lunar:
  - cinder/2:22.0.0-0ubuntu1.1, ironic/1:21.4.0-0ubuntu1, and senlin/1:15.0.0-0ubuntu1 fail on armhf due to an installation issue of mysql (probably bug #1980466)
  - python-caldav/0.11.0-1 on armhf: not investigated yet
* tzdata on focal:
  - postgresql-12/12.14-0ubuntu0.20.04.1 on amd64: not investigated yet
* tzdata on lunar:
  - chrony/4.3-1ubuntu4 on armhf: Flaky test case (see bug #2002910)
  - python-tz/2022.7.1-3: fixed by python-tz/2022.7.1-3ubuntu0.1
