Everytime I use Vpn I need to connect to the VPN manually using different countries.
Is there a way to connect to the VPN automatically after the system starts on Ubuntu 18.04? Thanks.
To automatically connect to VPN
Extra info on installing open VPN and use the same "settings, country" every time check this link.
In addition to AnOn's answer you might want to have a look at this answer. If you "Store the password for all users" then the VPN will also automatically connect after waking up from being suspended.
