systemd autopkgtests are failing in kinetic, and they are not considered regressions. The failing test is one within

FAILED (errors=1, skipped=2)

The failures started without any changes to the systemd package, i.e. it was caused by another package upload. In particular, the failures started around 2022-11-17 with linux 5.19.0-24.25. The tests pass fine with linux 5.19.0-21.21, i.e. the version in kinetic-release.

This can be demonstrated locally with autopkgtest:

$ autopkgtest --shell-fail systemd --test-name --pin-packages=kinetic=src:linux --setup-commands 'apt update' -- qemu /home/nr/ubuntu/autopkgtest-testbeds/autopkgtest-kinetic-amd64.img

Note in the above command I did not pass -U, so no packages in the test bed are upgraded. But, with:

$ autopkgtest --shell-fail systemd --test-name -U -- qemu /home/nr/ubuntu/autopkgtest-testbeds/autopkgtest-kinetic-amd64.img

the kernel is upgraded, and the test fails.

This can also be done manually by grabbing the systemd source on a kinetic machine (e.g. pull-lp-source systemd kinetic), and running:

$ sudo python3 test/ DnsmasqClientTest.test_resolved_domain_restricted_dns

The attached journal.txt shows systemd-resolved logs from when the test is run. The failure is caused by the EHOSTUNREACH when trying to resolve math.lab.
