How to set up OpenVPN in Ubuntu?

On Ubuntu, you use OpenVPN through the CopVPN Linux app. OpenVPN is built in, so there’s no server or config file to set up by hand.
1. Download CopVPN Setup from the Linux download page.
2. Allow it to run, then click Install and enter your computer password.
3. Open CopVPN and sign in with your email and the 6-digit code we send you, or with Apple or Google.
4. Choose a protocol: OpenVPN UDP, “Reliable and widely supported. Good if WireGuard is unstable.”, or OpenVPN TCP, “Slower, but gets through firewalls that block UDP, such as hotels, offices and schools.”
5. Pick a location and connect.
The app runs on 64-bit Ubuntu 22.04 or later, Debian 12 or later and systems built on them.
