Thanks for the update Robie. I was not aware of ntpdate being deprecated (appears to have been deprecated years ago).
For those like myself that require ntpd (the suggested alternative systemd-timesyncd uses sntp which may not suffice in all use cases), I think the best fix/workaround is to merely remove the ntpdate package. I didn't really use ntpdate anymore and suspect it was still installed from an earlier version of Ubuntu in my case (I've performed a fair number of inline upgrades on system). Historically, ntpdate was run prior to starting ntpd in case the clock was too far off for ntpd to sync. In looking at the ntp package further, I see that /etc/default/ntp includes the '-g' option which allows ntpd to perform a one time sync that would accommodate a clock with any delta. This in itself makes ntpdate unneeded for those running ntp service. Additionally, ntpd can also be run with arguments to simulate behavior of ntpdate if needed. So, if I understand correctly, the ntp package really has no bug (at least related to starting at boot). Issue was really due to bug with deprecated ntpdate package which should be removed if running ntp anyway. -- 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/1577596 Title: ntpd not started when using ntpdate Status in init-system-helpers package in Ubuntu: Confirmed Status in ntp package in Ubuntu: Won't Fix Bug description: After updating from 14.04 to 16.04 on a number of my systems, ntpd no longer starts at boot on any of those systems. `systemctl status ntp` shows: ntp.service - LSB: Start NTP daemon Loaded: loaded (/etc/init.d/ntp; bad; vendor preset: enabled) Active: inactive (dead) Docs: man:systemd-sysv-generator(8) May 02 19:10:14 host systemd[1]: Stopped LSB: Start NTP daemon. May 02 19:10:17 host systemd[1]: Stopped LSB: Start NTP daemon. Manually starting it using `systemctl start ntp` works fine. However, systemd does not seem to want to start it automatically at boot time. As best as I can tell based on trial and error, there is something special about the combination of the service being named "ntp.service" and the service depending on network.target. However, I haven't been able to identify exactly what is causing this. If I copy the init script to any other name, everything works fine: cp /etc/init.d/ntp /etc/init.d/ntpd Edit /etc/init.d/ntpd and change "Provides: ntp" to "Provides: ntpd" systemctl enable ntpd # After a reboot, ntpd.service is started, but ntp.service is not. If I remove "$network" from the "# Required-Start: $network $remote_fs $syslog" line in /etc/init.d/ntp, then systemd starts it automatically ... But of course it is started before the network comes up, so it fails. If I replace /etc/init.d/ntp with a file containing only the following, systemd won't try to start it automatically at boot: #!/bin/sh ### BEGIN INIT INFO # Provides: ntp # Required-Start: $network # Required-Stop: $network # Default-Start: 2 3 4 5 # Default-Stop: 1 # Short-Description: Start NTP daemon ### END INIT INFO echo "script was run" >> /ntp.log If I rename that same dummy script to /etc/init.d/ntp2, it is started automatically at boot. However, grepping the systemd source code and my systemd config files for ntp doesn't seem to find anything that might cause this behavior: /etc/systemd# grep -iR ntp * timesyncd.conf:#NTP= timesyncd.conf:#FallbackNTP=ntp.ubuntu.com /lib/systemd# grep -R ntp * system/systemd-timesyncd.service.d/disable-with-time-daemon.conf:ConditionFileIsExecutable=!/usr/sbin/ntpd system/systemd-timesyncd.service.d/disable-with-time-daemon.conf:ConditionFileIsExecutable=!/usr/sbin/openntpd Binary file systemd-networkd matches Binary file systemd-timedated matches Binary file systemd-timesyncd matches What else can I do to debug this further?
