NetworkManager and OpenVPN not working together

[seagreen]

With this NixOS configuration, when I run the command:

nmcli con up id my_vpn_id

I get this error:

Error: Connection activation failed: The VPN service 'org.freedesktop.NetworkManager.openvpn' was not installed.

I'm looking into the openvpn package documentation in case I made an error setting it up, but if not there may be a problem with openvpn.

Probably missing to declare the dbus service in the nixos module.

[seagreen]

Are you talking about in the NetworkManager package? IRC directed me to this line so it looks like dbus is enabled there.

I'm using OpenVPN through NetworkManager itself, nmcli probably needs some wrapping to be supported.

I get the same error when using nm-applet, but since it works for you that makes me suspicious the problem's on my end.

@iElectric, an chance your NixOS config files are online? I'd like to try exectly what you've done and see if I can get it to work.

Got it working -- among other things I was missing the line users.extraGroups.networkmanager.members = ["root"];.

Here's the relevant part of my config and here's an English guide to what I did.

Thanks for the help guys.
