I am surely no gnome user, but if I run gnome-control-center in xfce, then I don't even get the "IPsec/IKEv2 (strongswan)" menu (with or without your patch). There is only VPN --> openvpn. ???
In the network manager applet on xfce I can configure a few strongswan config items (gateway, certificates, a few options), but I am not sure if others are missing. I do not know if we see the same config options. Would you mind to send a screenshot of your IKEv2 config menu in g-c-c showing the options that are supposed to be added by your fix? Probably the Ubuntu version is fine; no reason to install Debian. Thanx very much Harri
