Hi,
I just updated a server machine from F17 to F18. This server is running a local VNC session which I connect to via SSH. It's using an XFCE4 desktop environment.
The machine is running a lot of virtual machines and so far there was a virt-manager instance running in the VNC desktop.
After the upgrade to F18, virt-manager no longer starts:
Unable to connect to libvirt.
authentication failed: polkit: Authorization requires authentication but no agent is available.
So I checked and, yes, there's actually no agent running, there's no polkit-gnome-authentication-agent-1 process, as usual.
In the XFCE4 Session settings, starting the PolicyKit Authentication Agent is activated. But polkit-gnome-authentication-agent-1 simply doesn't start. When I try to start it from the command line, I only get an error message:
$ /usr/libexec/polkit-gnome-authentication-agent-1
(polkit-gnome-authentication-agent-1:5772): polkit-gnome-1-WARNING **: Unable to determine the session we are in: No session for pid 5772
The same message is in the vncserver log file, btw. I'm starting the XFCE4 desktop via `exec startxfce4 --with-ck-launch' and ck-launch-session starts and runs. What else can I do?!?
Thanks for any help, Corinna
