[pkg-apparmor] Bug#954655: apparmor autopkgtest doesn't work nice on ci.d.n infrastructure

Version: 2.13.3-7
X-Debbugs-CC: debian-ci at lists.debian.org
Control: affects -1 autopkgtest

Dear maintainer(s),

I'm not sure what's going on, but I wanted to at least inform you that
the apparmor autopkgtest is not working smoothly on the ci.debian.net
infrastructure. Something in the test is very often preventing
autopkgtest (the binary) from stopping and cleaning up the lxc container
within the 600 seconds it gets to do that, which leads to a tmpfail for
the apparmor autopkgtest and a still running lxc container on the
worker. Obviously there's a bug somewhere in either lxc and/or
autopkgtest, as you shouldn't be able to break the infrastructure in
this way, but maybe you have a clue what could be the cause of this and
help us to fix the underlying issue. Your autopkgtest itself normally
passes before causing the issue.

One thing that may be required in your test if the test itself doesn't
get updated is to mark it as isolation-machine although I'd like to
understand the issue a bit better to know for sure. We can see this
issue happening at least as far back as 2019-12-05 09:19:03 UTC on amd64
unstable, I haven't checked all the logs.

Paul
