Comment 19 for bug 1942195

Verification done per [Test Case].

Note: the adsys autopkgtest failure on impish/arm64 is unrelated to the samba upload:

1. The part of the test that exercises samba passes. The failure is in an unrelated test.
2. The autopkgtest run fails even with adsys from impish-release; the test failure is not a regression caused by the samba upload.
3. The issue was discussed with didrocks (adsys "upstream"), and he agrees there isn't anything pointing at samba in the test failure. Discussion happened in #ubuntu-devel on 2021-11-19 [1].
