This is almost certainly because you don't have the systemd-timesyncd
package installed, or you don't have the systemd-timesyncd service
enabled.
On a very quick glance, it seems the systemd-time-wait-sync service
should have been bundled into the systemd-timesyncd package when it was
split from the main systemd package, however I'll have to look closer to
see if there is some reason it wasn't.
** Description changed:
+ [impact]
+
+ systemd-time-wait-sync service never completes when systemd-timesyncd
+ package is not installed
+
+ [test case]
+
+ remove the systemd-timesyncd package and enable the systemd-time-wait-
+ sync service, and reboot. Check status of the service to see it's stuck
+ in 'activating' state, e.g.:
+
+ ubuntu@lp1937238-f:~$ sudo systemctl status systemd-time-wait-sync.service
+ ● systemd-time-wait-sync.service - Wait Until Kernel Time Synchronized
+ Loaded: loaded (/lib/systemd/system/systemd-time-wait-sync.service;
enabled; vendor preset: enabled)
+ Active: activating (start) since Fri 2021-07-23 15:32:12 UTC; 19s ago
+
+ [regression potential]
+
+ TBD
+
+ [scope]
+
+ this is needed in f and later
+
+ the systemd-timesyncd package was split out from the main systemd
+ package starting in focal, so this problem exists in f and later
+
+ the service doesn't exist in b, so this is not needed there
+
+ [original description]
+
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:
