I have an Ubuntu virtual machine which I access via SSH. When I execute the who command I get nothing. Moreover I get this output when executing systemctl --user:

Failed to connect to bus: No such file or directory

When executing systemctl status dbus I get everything normal except for this line:

[system] Failed to activate service 'org.freedesktop.login1': timed out (service_start_timeout=25000ms)

The output before log is:

dbus.service - D-Bus System Message Bus

The output of systemctl status systemd-logind is:

Any suggestion about what is going on?

So now we've isolated the problem to the `logind` service failing - so far so good.

Ok but why does `logind` fail?, I tried everything to trace the issue with no luck

Yeah, to that I haven't got a clue..

Is there any additional information in the journal (ex. `journalctl -xe -u systemd-logind.service`)?

No the same error message

The problem was solved - the directory /var/run should be symlink to /run, but for an unknown reason it was not.

Please refer to: Is my /var directory OK, since /var/run isn't a symlink?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
