Gnome Network Manager VPN Tab Disabled ( Greyed out )

Posted on in Categories , last updated September 8, 2016

I‘ve the NetworkManager service is installed and started under Linux desktop. The applet is running. The NetworkManager can display available network hardware and wireless networks. But, I’m unable to add VPN support as the Add tab is greyed out. I need to use both PPTP and Cisco vpn clients. How do I fix this problem under Debian or Ubuntu Linux?
