I just wanted to chime in here as I was having the exact same problem. Turned out to be because of some configuration changes I made to ntp.conf in an attempt to prevent ntpd from listening on any of my network interfaces (security paranoid):
interface ignore wildcard interface listen 127.0.0.1 Apparently ntpd also uses these settings for outgoing connection attempts too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1797872 Title: ntpd keeps Soliciting pool server To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ntp/+bug/1797872/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
