These steps are assuming you’ve already got wireguard setup and have a .conf file.
Ensure Wireguard is installed
sudo apt install wireguardMove the .conf file to the Wireguard folder
Your wireguard conf file may be named something else, but mine is wg0.conf
sudo cp Downloads/wg0.conf /etc/wireguard/Start Wireguard
Use the correct name for your wireguard config file. Note that I use wg0 because my file was wg0.conf.
sudo wg-quick up wg0Fix wg-quick: line 32: resolvconf: command not found error
This step is optional, you only need to do this if you got the above error.
ln -s /usr/bin/resolvectl /usr/local/bin/resolvconfDisconnect from Wireguard
sudo wg-quick down wg0
