Ubuntu 17.10 (Artful Aardvark) has reached end of life, so this bug will not be fixed for that specific release.

I believe this may be a bug in dh_systemd_start: # Automatically added by dh_systemd_start if [ -d /run/systemd/system ]; then systemctl --system daemon-reload >/dev/null || true if [ -n "$2" ]; then _dh_action=try-restart else _dh_action=start fi deb-systemd-invoke $_dh_action apt-daily-upgrade.timer apt-daily.timer >/dev/null || true fi # End automatically added section This reduces to: deb-systemd-invoke try-restart apt-daily-upgrade.timer apt-daily.timer >/dev/null || true which is (after calling/checking policy-rc.d) is: systemctl try-restart apt-daily-upgrade.timer apt-daily.timer >/dev/null || true This is correct, for the apt-daily.timer and does nothing for the apt- daily-upgrade.timer. Since apt-daily-upgrade.timer is not active, try- restart does not start it. Imho, there should be an extra snippet in apt.postinst which does this: if [ -d /run/systemd/system ]; then if dpkg --compare $2 with version that introduces apt-daily-upgrade.timer; then deb-systemd-invoke start apt-daily-upgrade.timer >/dev/null || true fi fi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1707880/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
