system is booting up. see pam_nologin (8)

[Frédéric]

Hi,

This morning after booting, I can see the screen of sddm, fine.
But nobody can login from from there.
Going to a terminal, we can see this message:
system is booting up. see pam_nologin (8)

We discovered a /run/nologin file that we had to remove.

The log is provided below.

Any idea what is the cause of that?

Hi,

I searched a bug description:

    This is actually a bug. I've been seeing this myself and it appears
    I am not alone.

    Rebooting is just a workaround that fixes this _sometimes_ and its
    sheer luck, due to a race condition. The issue seems to be affecting
    other distro's too and seems to be due to a stale /run/nologin file
    being left lingering after boot, making login impossible. So its not
    really solved at all until the underlying race condition (bug) gets
    fixed.

    If you ctrl-alt-f1 and login as root and remove /run/nologin all
    will be well (for a little while).

    Please see the following links where its explained in more detail:

    https://bugzilla.opensuse.org/show_bug.cgi?id=980324

    Bug filed with systemd author:

You can reboot to try solve it.

or, just remove |pam_nologin.so at /||etc/pam.d/sshd|

When I had this exact problem, it was because of this bug:
