IDK why this happened and why he service is missing on your system, but to circumvent the issue you can select Change command and just type true and hit return, it should continue then without the time sync check. But if your system time is out of sync this could lead to new problems, so I recommend to make a backup before you try that.
yes, this time it worked. I think, as I switched to timesync mode “custom”, the dietpi update was running through without an issue, it solved the problem with reinstallation of systemd-timesyncd.
I’m not sure, but maybe at some point I was playing around with NTP / SNTP and installed the ntp package that (maybe?) deactivated systemd-timesyncd.
Yes because we don’t trigger the time sync anymore. But this would require another time synchronisation service, otherwise your system will run out of time sync. Because our service has been disabled now.
