Package: systemd Version: 231-4 Doing
Setting up systemd (231-4) ... addgroup: The group `systemd-journal' already exists as a system group. Exiting. while nodm is running knocks the user into a black screen. To recover: CTRL ALT F1, then login, then do chvt 7... perhaps some users won't figure out how to recover... Seen on each of my several computers.
