Well, had to update to KUbuntu 11.10 the other day (the KDE-menu hung frequently, since I’ve added window managers galore and… well, it was all a bit unstable in the end).
One thing I noted was that my Cisco VPN connections didn’t work, despite being able to import the PCF files. Nothing happened when trying to activate the VPN. Found a tip that the plugins needed were missing, and after installing the needed vpnc plugin I was connected.
So, all I did was;
sudo apt-get install network-manager-vpnc
… and it Just Worked.
