This question already has an answer here:
The Title says it all. We just got a Raspberry 2 with a Debian Linux on it. After hitting 'Startx' the windows come up and we get this message:
GDBus.Error.org.freedesktop.PolicyKit1.Error.Failed: Cannot determine user of subject
After hitting ok, all seems to work well, but I'm wondering what it means?
With the idea that "It's better to teach a man to fish than give him fish", if possible, tell me where you look these errors up. Is it possible to tell if it's Linux, Debian, or Raspberry specific? As you can probably tell, I'm completely new to Raspberry, Linux, and Debian.
