## Error: WireGuard exited with the error: Cannot find device "wg0"
|
|
|
|
This error indicates that the WireGuard interface `wg0` does not exist. This can happen if the WireGuard kernel module is not loaded or if the interface was not created properly.

```shell
|
|
echo "wireguard" | sudo tee -a /etc/modules
