when installing systemd, it creates /run/nologin preventing all users from logging in.

[tim.tadh]

How to replicate:

sudo apt-get install systemd

wait for 5 minutes

check to see if /run/nologin appears. If it does the bug is present. See https://ubuntuforums.org/showthread.php?t=2327330

I ran this command via ansible on all of my servers. Then I could no longer log into any of them. Pretty big bug in my opinion. Please fix.

Status changed to 'Confirmed' because the bug affects multiple users.

Thank you, today my Ubuntu 16.04 booted into the maintenance mode and systemctl --failed showed only nfs-resolvd.service. I made
# systemctl restart ssh
then I got:
"System is booting up. See pam_nologin(8)"
Authentication failed.

# rm -fv /run/nologin
solved the issue.

I ran
# apt install --reinstall systemd
and /run/nologin did not appear again.

[Mikhail Novosyolov (mikhailnov)]

I got this again.
Commented out the line
auth requisite pam_nologin.so
in /etc/pam.d/login

Now /run/nologin must be ignored and do not prevent the system from booting up correctly, but this bug must be marked as CRITICAL, I think.

Deploy Ubuntu Bionic machine from AWS, try and log in:

"System is booting up. See pam_nologin(8)"

Given it is impossible to log in, it's impossible to see what's wrong, or fix it.

Graham, you could be hit by a different bug. (In my case it was fubared NFS mount from fstab – turns out NFS mounts should be removed from fstab before upgrades) You are interested in solving "pam_nologin should allow sudoers to log in" – it is bug #1847902

please reopen if this is still an issue
