I tested the suggestion from comment #38 by robx. ======== It works for me.
Deviating from his proposal I only did the following change: hhl@ILS-AP2:~$ diff ntpdate /etc/network/if-up.d/ntpdate 9a10 > # exit 0 # hh_161120 - ntpdate prevents start ntpd Ubuntu Bug #1577596 42c43,44 < flock -n /run/lock/ntpdate /usr/sbin/ntpdate-debian -s $OPTS 2>/dev/null || : --- > # avoid conflict with ntpd: option -u have ntpdate-debian use a non > priveledged source port > flock -n /run/lock/ntpdate /usr/sbin/ntpdate-debian -su $OPTS 2>/dev/null || : hhl@ILS-AP2:~$ If -u is specified for ntpdate-debian it might also be possible to bypass stop/start of ntpd sind ntpdate and ntpd are no longer in conflict for port UDP/123. I hope there is no race for other resorces (hwclock?). I did disable stop/start and it works for me. hhl@ILS-AP2:~$ diff ntpdate /etc/network/if-up.d/ntpdate # disabling ntpd stop/start ... 39c40,41 < invoke-rc.d --quiet $service stop >/dev/null 2>&1 || true --- > # stopping service ntp is no loger required if ntpdate-debian is not using > source port UDP/123 > # invoke-rc.d --quiet $service stop >/dev/null 2>&1 || true ... 44c47 < invoke-rc.d --quiet $service start >/dev/null 2>&1 || true --- > # invoke-rc.d --quiet $service start >/dev/null 2>&1 || true hhl@ILS-AP2:~$ I still think package ntpdate should not be in the system unless explicitely requested. I suggest package ntpdate to be modified to include option -u when invoking ntpdate-debian. The thorough analysis of what went wrong was done by others - see comments. I am confident a simple change solves the bug and that it works in general and not only for me! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577596 Title: ntpd not started when using ntpdate To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/init-system-helpers/+bug/1577596/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
