This is a known issue for DBus unit tests in CI / buildd
infrastructures. (I don't remember the full details / the bug number,
but it is a problem caused by the interplay of libpam-systemd and schroot.

Hmmm... maybe something similar is happening in lxc based builds
(autopkgtests use lxc, iirc)?

ci.debian.net is using lxc, yes, autopkgtest has much more backends.

We could try bumping the debhelper compat level to version 13 (currently
11). That helped with libqtdbustest and libqtdbusmock a few months back.

Would that be an RT compliant solution?

https://release.debian.org/bullseye/FAQ.html last paragraph.

So, what in compat level 13 is different for you that actually fixes the
issue? Obviously if you can show in the necessary unblock request that
the *only* delta of bumping compat level is the part that fixes this
bug, we'd accept. But that would require you to e.g. run diffoscope on a
build with and a build without the bump, as we can't judge the changes
from source alone.

I have now uploaded a dbus-test-runner with minimal changes to experimental (dbus-test-runner_16.10.0~bzr100+repack1-5~exp1).

Can you re-run those autopkgtests multiple times on ppc64el and check if the flakiness has now vanished with debhelper compat level bumped to version 13? Thanks.

Mike
