Ubuntu – ntp doesn’t sync – Server has gone too long without sync

ntpdUbuntu

I'm unable to sync with ntp server. Any suggestions on how to force the ntpdate to work and sync?

ntp.conf on clients are default with only the server address changed.

ntpdate -dv 10.10.10.10

Best Answer

Note the reference time received back from the server: Wed, Jun 20 2018 20:42:16.015 - that means that the server has not syned with its upstream(s) since that time. ntpdate considers this too long ago and will not sync with that server because it's probably giving bad time. To fix ntpdate you need to fix the server.
