This bug was fixed in the package systemd - 237-3ubuntu3
---
systemd (237-3ubuntu3) bionic; urgency=medium
* tests/control: drop qemu-system-ppc.
Whilst some tests pass, many regress / fail to boot. This is not a
regression,
as qemu-based tests were not run previously.
Thank you!
This does appear to be the problem, that 95-dm-notify.rules are now
shipped in the package, but were not copied in the test harness.
