Thanks for the reply, but on the step one says:
Step One: Check Requirement
In order for you to be able to configure WireGuard VPN client with NetworkManager GUI, you need NetworkManager with version 1.26.2 or higher.
I use Wireguard daily in terminal with Multiple VPN profiles and its just easy use the GUI.
If i use any free distro i get the GUI, Pop, Mint, Ubuntu, etc. I paid for the Zorin 16 but probably on Zorin 36 when no one uses WG and moved to another VPN protocol Zorin team update the package.
If i add Ubuntu repository install the updated package and remove the repository will work??
