I was looking for the "x2gosuspend-session-gnome" command, so I installed apt-file and updated it, but then I received an error message:
Ignoring source without Contents File: http://apt-mirror/x2go/dists/lenny/Contents-amd64.gz
Obviously, apt-mirror is my local mirror. I've had no other problems with it.
Thanks,
