When I start my server running Ubuntu 20.04 the systemd-time-wait-
sync.service is stuck in "activating" state. I noticed this because none
of the systemd timer units triggered, because all the timers depend on
systemd-time-wait-sync.service. Running "systemctl restart systemd-time-
wait-sync.service" manually works around the problem.
Some logs and command outputs:
