Trying to install VPN and these are the instructions Mullvad is giving me. This is ridiculous. There must be a more simple way. I know how to follow the instructions but I have no idea what I'm doing here. Can't I just download a file and install it? I'm on Ubuntu.
Hmm... ProtonVPN team solved this in better way. They put the repo configuration stuff into DEB file, so it's just a matter of double clicking it and clicking install on Debian-based and Ubuntu-based (I know Ubuntu is Debian-based) distros and then installing the ProtonVPN client through either GUI or CLI package manager, whichever you wish to use. More newbie-friendly.
Unfortunately, I also just learned they dropped support for Arch Linux :(
