Hello Mark, Debian chrony maintainer here.
So, this error occurs when attempting to rehabilitate systemd-timesyncd when uninstalling/purging chrony (see restore_timesyncd() in d/postrm). This used to be possible when systemd-timesyncd and chrony were co-installable but since systemd 245.4-2{,ubuntu1}, this is no longer the case because systemd-timesyncd is now a standalone package conflicting with chrony, hence the exit status 1. To fix this, the restore_timesyncd() function found in the chrony 3.2-4ubuntu4.2 postrm script should be updated as follows: restore_timesyncd() { # on next reboot it would start, but that would leave time # unsynchronized until then. So as the Conflicts in the service file # kill systemd-timesyncd re-establish it if it is enabled if [ -d /run/systemd/system ]; then deb-systemd-invoke start systemd-timesyncd || true fi >From what I can see, the chrony version found in Disco Dingo is also be affected by this issue.
