I’m using Nobara and I can’t seem to find a way to download surf shark. They have a terminal command that installs it automatically, but it’s a .deb file. I’m pretty sure Nobara is fedora. I don’t think I can use that.
Based on How to set up Surfshark on Linux – Surfshark Customer Support, only a few distributions are officially supported. The distribution you are using is not one of them.
However, there is apparently a snap version (Install Surfshark VPN — safe & private online on Fedora using the Snap Store | Snapcraft). With a bit of luck, this will also work under Nobara as this distribution is apparently based on Fedora.
some VPN services can be used with the OpenVPN tools commonly found in many linux Distros.
