When I turn on my raspberry, I get this error message:
GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: An authentication agent already exists for the given subject
After a I did a small search about it, it turned out that it happens because there is more than one "PolicyKit" package installed, and I should only keep one.
I used the following command to list the available "PolicyKit" packages:
- Code: Select all
[b]dpkg --get-selections | grep polkit[/b]
Which one should I keep?
