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.

New Linux user here. Is this really how I'm supposed to install apps on Linux? (feddit.uk)

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.

As others have mentionned downloading the .deb and running it will also work, but I feel nobody gave your a tldr of why you may want to follow those instructions instead, so here it is:

Those instructions configure your package manager (apt) with a new repository for this application.

The upside to that is that anytime you will look for updates, this app will also get updated.

It's a bit more work up front, but it can pay off when you have dozens of app updating as part of normal system operations.

Imagine a world where windows updates would also update all your software, that's what this is.

Also, no, this is not an ideal way to do this. Ideally every package you want is in your distro's repos so you'd just need to do "apt install [package]".

The reason this one isn't is because mullvad wants to make sure you use their tested, secure, and updated version and they don't want to maintain that for every distro. So they have you configure your package manager to use their repos.

This is relatively uncommon to come across in Debian. You'll normally only find it in security applications or very niche ones. The Debian repos aren't the most comprehensive but they'll contain the vast majority of common softwares.
