By default, GNOME 3's VPN configuration tool for NetworkManager supports IPSEC VPNs, but not WireGuard. I want WireGuard support because:

• I can import settings from a WireGuard config file.
• I can link that VPN connection to another connection (e.g. a mobile device via Bluetooth), so that it runs automatically.

Some kind and clever person has created a plugin.

I followed the guidance here to install it.

The guide almost worked for me, but I needed an extra package (intltool).

Here's what worked for me:

sudo apt install build-essential libgtk-3-dev libnma-dev libsecret-1-dev intltool -y
git clone https://github.com/max-moser/network-manager-wireguard
cd network-manager-wireguard
./autogen.sh --without-libnm-glib
./configure --prefix=/usr 
              --without-libnm-glib 
              --sysconfdir=/etc 
              --libdir=/usr/lib/x86_64-linux-gnu 
              --libexecdir=/usr/lib/NetworkManager 
              --localstatedir=/var
make   
sudo make install

(I note that the plugin uses the name "Wireguard", but the trademarked name is "WireGuard". Oh well.)
