I don't manage to setup my VPN clients. I've just upgraded to 13.10 but I already had the problem with Ubuntu 12.04.
With Ubuntu 12.04 my problem was the same as this thread Can't add VPN connection to network manager, that is the Add button on the VPN tab of the network manager was greyed out. I tried to install some vpn packages as advised, but they were already installed:
sudo apt-get install network-manager-pptp network-manager-vpnc network-manager-openvpn Reading package lists... Done Building dependency tree Reading state information... Done network-manager-pptp is already the newest version. network-manager-openvpn is already the newest version. network-manager-vpnc is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I hoped this would be fixed installing Ubuntu 13.10, but now when I try to add a VPN network using the "+" button, I got the following message:
Error creating connection Don't know how to create 'NMSettingVPN' connections
It seems to be a bug but I have no idea how to fix it (sorry, I'm just a poor newbie...). Might these be due to conflicts among several VPN plugins/packages?
If someone could indicate me the cleanest way to fix this, I would greatly appreciate. Many thanks in advance.
