Dbus/Systemd. No XDG_* Variables. systemctl --user fails

Hi!

Lately i discovered, that executing `systemctl --user` as an user or as root on my headless server yields:

Failed to connect to bus: No such file or directory

The same with `busctl --user`. `busctl` on its own runs fine.

While stepping deeper into the problem i noticed that `systemctl start user@username` would generate following error:

Dec 16 22:25:54 jarvis systemd[6430]: Failed to create generator directory /run/user/1000/systemd/generator: Permission denied
Dec 16 22:25:54 jarvis systemd[6430]: Failed to fully start up daemon: Permission denied
Dec 16 22:25:54 jarvis systemd[6430]: Failed to load default target: No such file or directory
Dec 16 22:25:54 jarvis systemd[6431]: pam_unix(systemd-user:session): session closed for user nuke
Dec 16 22:25:54 jarvis systemd[6430]: Trying to load rescue target...
Dec 16 22:25:54 jarvis systemd[6430]: Failed to load rescue target: No such file or directory
Dec 16 22:25:54 jarvis systemd[1]: Started User Manager for UID username.

An ls in /run/user/ showed me that the directory was empty.

I didn't see any other errors in my logs. Maybe I'm missing something.
Did anyone encounter a similar issue or can point me in the right direction?

Dmesg output, just in case:

If you need more logs or command outputs, just say it, I will deliver as fast as possible.

Edit:

I stumbled upon another issue. It looks like there are no XDG Variables defined. There is only $XDG_DESKTOP_DIR=/root/

The other variables are missing:
- XDG_RUNTIME_DIR
- XDG_SEAT
- XDG_SESSION_ID
- XDG_VTNR

Re: Dbus/Systemd. No XDG_* Variables. systemctl --user fails

Hi,

Not very helpful but the missing XDG_* variables and systemd-vconsole-setup.service failing to start according to your dmesg make me think you haven't got a fully functioning systemd-logind session. The best I can suggest is having another read of the systemd and installation guide pages of the wiki and seeing how your system compares.
