I installed sudo apt-get install network-manager-pptp and set up a vpn profile configured to connect to my schools vpn but when I Click on it under my network icon, "VPN Connections." nothing happens. When looking back the vpn connection gets a check mark but that is it. Making other profiles leads to the same result. Also more then one can be checked at a time. I tried using nmcli but got an error

nmcli -p con up uuid bd42a0f6-77ae-45e2-b38d-aec16a9bc51e
Error: No suitable device found: no active connection or device.

I am connected to the internet though eth0 and everything else works. Any thoughts?
