I am trying to setup NTP 4.2.8p17 on ubuntu 24.04 LTS

But while running ntpd.service as systemd i have encountered below error-
18 May 10:59:45 ntpd[23215]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized
18 May 10:59:45 ntpd[23215]: kernel reports TIME_ERROR: 0x41: Clock Unsynchronized
18 May 10:59:45 ntpd[23215]: ntpd exiting on signal 15 (Terminated)

systemd-

There might be more information about why ntpd terminated in /var/log/ntp.log at that time. If that doesn’t shed light, you might try running ntpd with the same command line from a root shell to see if there are any helpful messages.
