dietpi-update fails Error:
[FAILED] DietPi-TimeSync | systemctl start systemd-timesyncd
Luckily it asked for an alternative command:
[ INFO ] DietPi-TimeSync | Executing alternative command: chronyc tracking
200 OK
[ OK ] Alternative command execution | Completed
chronyc tracking, is the alternative command fix for this.
A check for chronyd, and using chronyc tracking instead of systemctl start systemd-timesyncd would be a good fix.
Would also be nice to see chrony in the dietpi-software list
