[PROBLEM] VPN with Xbian?

[Nachteule]

Sorry, but gradually you really kill my last nerve

Your sudo configuration is still NOT working

First test what you did in the command line (user xbian)

Terminal

sudo /usr/bin/killall

sudo /usr/sbin/openvpn

Both commands must not ask you for a password. Only after that, you can continue with the openvpn addon
And make sure that in Advanced Settings "openvpn path" is set correctly and "Use openvpn with no path" is not enabled
