Comment 11 for bug 1946521

I can confirm that motion from mantic-proposed has fixed the bug for me.

Test done:

Install motion on a mantic installation.
confirm that motion service did not start and the issue is seen.

Add mantic-proposed to apt sources
update motion from mantic-proposed
check that the motion.service is running

$ systemctl status motion.service
● motion.service - Motion detection video capture daemon
     Loaded: loaded (/lib/systemd/system/motion.service; enabled; preset: enabled)
