When attempting to launch
system-config-users from command line, I get the following warning, and the tool does not open. I'm using CentOS 7 with Mate 1.8.1.
WARNING **: Error enumerating actions: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.PolicyKit1 was not provided by any .service files

What system component is responsible for the problem?
I just had the same return when installing deluged on arch, i typed.
systemctl start deluged
I tried using sudo and it worked fine It seems to be a group permissions issue
I just enabled the user account and then started typing
sudo systemctl start deluged
worked like a charm.
