I have created an OpenVPN connection to GigaNews' VyperVPN but it doesn't connect. I followed all of their procedures found here:
In my /var/log/syslog I find this:
Mar 4 16:57:45 X123 NetworkManager[1511]:
<warn> connection /org/freedesktop/NetworkManager/Settings/0 failed to activate:
(1) Could not find source connection, or the source connection had no active device. 1 1 Answer

It involves installing the OpenVPN Network Manager and tweaking a few settings.
