From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

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

I was wondering how they'd solve signature checking and key installation - and looking at their page they seem to recommend skipping checking package signatures which, to be honest, isn't a super good practice - especially if you're installing privacy software.

Please don’t try to check the GPG signature of this release package (dpkg-sig –verify). Our internal release process is split into several part and the release package is signed with a GPG key, and the repo is signed with another GPG key. So the keys don’t match.

I get it's more userfriendly - and they provide checksums, so not a huge deal, especially since these are not official Debian packages, but the package signing has been around since 2000, so it's pretty well established procedure at this point.
