I'm seeing same behavior as Alex where failure of ntpdate is preventing ntpd from starting. ntpdate is logging same message indicating failure due to name resolution (Bind not running yet at boot):
Sep 16 10:40:09 scorpion ntpdate[1033]: name server cannot be used: Temporary failure in name resolution (-3) The script /etc/network/if-up.d/ntpdate does attempt to stop any running ntp service prior to running ntpdate but then exits without restarting ntp if ntpdate-debian fails. I modified /etc/network/if-up.d/ntpdate to only log a message and exit as a workaround and ntpd now starts at boot. I'm still a bit puzzled why ntpd doesn't attempt to start after /etc/network/if-up.d/ntpdate fails (multiple times in my case due to multiple interfaces on host). When /etc/network/if-up.d/ntpdate runs/fails, there is no log message from ntp indicating it tried to start (neither before nor after ntpdate fails). However, after applying my workaround, the log message for ntp service is one second after last run of /etc/network/if-up.d/ntpdate. I would have thought that the failure of ntpdate would not prevent the later startup of ntp. I'm guessing that /etc/network/if-up.d/ntpdate initiates a stop in parallel to systemd start of ntpd before it logs anything to syslog. -- 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: Confirmed 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?
