The only server ntpdate found for update had a problem returning the date for your server. That can be some things:

  • If it was only this time, on this server, it could be a temporary issue and you should try again (since you are using pool.ntp.org and that points to various different servers);
  • If it happens with all the ntp servers you try, you can be behind a firewall that blocks ntp traffic or
  • You can have a bug or a config issue.

It means the server you are getting connected to either was not giving out the time (I just check it, it is working fine at this moment) or your network doesn't let you talk to it on the right ports. Maybe you are behind an overly restrictive firewall?
