When I don't have chrony installed, timesyncd is running: root@bionic-chrony:~# systemctl status systemd-timesyncd chronyd Unit chronyd.service could not be found. ● systemd-timesyncd.service - Network Time Synchronization Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled) Active: active (running) since Wed 2018-07-04 19:40:37 UTC; 13s ago Docs: man:systemd-timesyncd.service(8) Main PID: 521 (systemd-timesyn) Status: "Idle."

The moment I install the chrony package, timesyncd is stopped: root@bionic-chrony:~# apt install chrony Reading package lists... Done Building dependency tree Reading state information...
