I have a Pi Zero running Pi-Star v3 for over a year without any issues... yesterday I upgraded to Pi-Star v4 and have rebooted the PiZ multiple times but ntp time is not syncing. I stopped the ntp service and attempted to run "sudo ntpdate pool.ntp.org" but get "sudo: ntpdate: command not found". I also checked to make sure the service was running:

As I read this, it is attempting to sync with ntp servers. I can also ping the servers on the list.

SO... I'm at a loss to determine why ntp is not working. Anyone have any ideas?

KE7FNS,

Thanks... I don't have this problem with my other Pi-Star (its running v3) so do you think they left the ntpdate package out of v4?

Also, even though I don't have the ntpdate package installed, do you agree ntp is attempting to sync? When I look in the ntp.conf file, it does have the pool servers listed.

I was using this to monitor ntp syncing

Much thanks for the timedatectl command... wasn't aware of that. But running it confirms my PiZ is not syncing so the search for a solution continues.

Tell me about it... I have a few Beaglebones and R-Pis lying around, and periodically I'll boot them in order to do "sudo apt update; sudo apt upgrade" sequences... And too many time have had the "update" step fail with "repository validity time in the future"... I have to wait for the time sync to complete and redo the command.
