Thank you for taking the time to report this bug and helping to make Ubuntu better.
Do you want NTP to listen on all addresses? That is not typically what someone will want. That is why there is the -I option (e.g. -I 127.0.0.1) that can be added to the command line in /etc/default/ntp to listen on a specific port or address. Since there isn't enough information in your report to differentiate between a local configuration problem and a bug in Ubuntu, I'm marking this bug as Incomplete. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New. If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community ** Changed in: ntp (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ntp in Ubuntu. https://bugs.launchpad.net/bugs/1649729 Title: ntpd startup failures under xenial Status in ntp package in Ubuntu: Incomplete Bug description: I have a system running 16.04.1 with multiple interfaces configured via /etc/network/interfaces. Following a restart, ntpd will often be found not running, despite being installed and configured. syslog suggests ntpd is being repeatedly stopped and restarted within seconds.

The rapid stop/start cycle of the daemon appears to trip up the port binding, and eventually cause ntpd to become unhappy and wind up stopped. Manually restarting ntpd (or even running /etc/network/if- up.d/ntpdate) outside of interface up/down time properly brings up ntpd. It doesn't appear to be a configuration issue as such. Further, running /etc/network/if-up.d/ntpdate from bash several times in rapid succession also produces the 'missing ntpd' behavior, outside of the context of any interface activity.
