fixing VPN problem in Ubuntu

I set up VPN in Ubuntu 14.04, but when I tried to turn it on in NetworkManager, I kept getting errors like "No suitable device found", "Could not find source connection" in /var/log/syslog.

The problem turned out to be that my ethernet connection was not managed by NetworkManager. "nmcli c" didn't show my wired connection.

The solution:
Edit /etc/NetworkManager/NetworkManager.conf, in section [ifupdown], change "managed=false" to "managed=true", then do a:
"sudo service network-manager restart"
Now both vpn and ethernet connections are managed by NetworkManager, turning on VPN just works.
