Proton VPN has been one of the best VPNs for years, but the #Linux experience has never quite been up to par with Proton VPN on Mac, Windows, or mobile platforms. That's now changing, as Proton is releasing a feature-complete version of its desktop app for Linux PCs.
If you want to check out the new desktop app, it's officially supported on Debian, Ubuntu, and Fedora.
@AskTheDevil Proton offer a good free version for the VPN also
worth trying before you commit
obvs you are limited with features using free version but it gives at least a guide as to the service and stability of the app
