Why does hosting Lemmy require a display? (aussie.zone)

I'm trying to set up my own Lemmy server with Docker. I think I have everything set up, but I'm getting an error Cannot autolaunch D-Bus without X11 $DISPLAY. This error kind of makes sense, because I'm SSHing into my server and have not forwarded D-Bus connections, so $DISPLAY is undefined. But why does a Lemmy server need a display in the first place? Is this a bug and a display isn't actually needed? If I set $DISPLAY to whatever, will it still run okay?

The problem is likely Ubuntu not Lemmy or not even the Lemmy setup process.

You seem to not have a dbus session going which you should by default even with SSH. It sounds like it might be falling back to trying to get it from X11 and fails that too (obviously).

So, just Ubuntu being Ubuntu.
