Chances are some package has written /run/nologin file.This can happen if you run "systemd-tmpfiles --create" which perhaps some package might still do in it's %post.... A reboot should clear out this problem. I'm not 100% sure but I think root logins should also still be allowed even with a nologin file... could be wrong tho'. Col
I can't do reboot. The system will become responseless if I gave shutdown/restart/logout
