Download the binaries. I think I downloaded the RPM files. There should be instructions on where to put the files in the file. You might need to look up a guide to installing binaries manually.
Once you’re done, you can run Windscribe via command line and it works great.
I’ve been waiting for Windscribe or someone to port the Linux version to Solus. As it stands, the only decent free VPN that can be used via OpenVPN is the free version of ProtonVPN, which while is it quite decent for being free, it doesn’t work with torrents.
I have a free account with 50gb, going to be annoying not being able to use it. Might have to set up a VM for when I do need to torrent something with VPN.
