Observation¶

I encounterd this error before. At that time, I can get over it by upgrade xterm-console and then re-install os-autoinst.
This time I did not perform the exact same sequence of operations as before, but still tried to resolve this issue by various method.
Unfortunately, this error persists and block me from continuing my test.

Acceptance criteria¶

• AC1: There is clear feedback that the apparmor profiles are not compatible with remote backends

Suggestions¶

• From within the worker, when the backend for a job is not qemu, try to conduct an operation which is only allowed with apparmor disabled, e.g. something with "ssh", report an obvious message if not
• As an alternative: Add a check to the worker calling sudo /usr/sbin/aa-status | grep '/usr/share/openqa/script/worker' whenever the backend is not qemu. But research if we can achieve that without root permissions
