Ok, could you please attach these files: /lib/systemd/system/chrony.service /lib/systemd/system/systemd-timesyncd.service
And if there are equivalent ones in /etc/systemd, those too. They could be overriding settings from the ones in /lib. You might want to run this to find them: find /lib/systemd/ -name 'chrony.service' -ls -o -name 'systemd- timesyncd.service' -ls Same for /etc: find /etc/systemd/ -name 'chrony.service' -ls -o -name 'systemd- timesyncd.service' -ls On a working system, with both installed and where chrony is the only one starting up, I get: root@bionic-chrony:~# find /lib/systemd/ -name 'chrony.service' -ls -o -name 'systemd-timesyncd.service' -ls 1801 4 -rw-r--r-- 1 root root 1342 Apr 20 16:55 /lib/systemd/system/systemd-timesyncd.service 63916 4 -rw-r--r-- 1 root root 567 May 23 14:21 /lib/systemd/system/chrony.service root@bionic-chrony:~# find /etc/systemd/ -name 'chrony.service' -ls -o -name 'systemd-timesyncd.service' -ls 1871 0 lrwxrwxrwx 1 root root 34 Jul 5 18:16 /etc/systemd/system/multi-user.target.wants/chrony.service -> /lib/systemd/system/chrony.service 627 0 lrwxrwxrwx 1 root root 45 Jun 1 14:06 /etc/systemd/system/sysinit.target.wants/systemd-timesyncd.service -> /lib/systemd/system/systemd-timesyncd.service -- You received this bug notification because you are a member of Ubuntu Server, which is subscribed to chrony in Ubuntu. https://bugs.launchpad.net/bugs/1779621 Title: chrony exits unexpectedly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/1779621/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
