When I start systemd as root on my linux mint 18.2 vm it gives me the following error message :
Trying to run as user instance, but $XDG_RUNTIME_DIR is not set.
I checked the $XDG_RUNTIME_DIR as user and it gave me /run/user/1000, but i am not able to run systemd as user as it then gives me this error :
Failed to create /user.slice/user-1000.slice/session-c2.scope/init.scope control group: Permission denied
Failed to allocate manager object: Permission denied
When i am root the command "echo $XDG_RUNTIME_DIR" gives me no output.
Any possible solutions?
