So usually people do install Linux software from trusted software repositories. Linux practically invented the idea of the app store a full ten years before the first iPhone came out and popularized the term “app.”

The problem with the Mullvad VPN is that their app is not in the trusted software repositories of most Linux distributions. So you are required to go through a few extra steps to first trust the Mullvad software repositories, and then install their VPN app the usual way using apt install or from the software center.

You could just download the “.deb” file and double click on it, but you will have to download and install all software security updates by hand. By going through the extra steps to add Mullvad to your trusted software repository list, you will get software security updates automatically whenever you install all other software updates on your computer.

Most Linux distros don’t bother to make it easy for you to add other trusted software repositories because it can be a major security risk if you trust the wrong people. So I suppose it is for the best that the easiest way to install third-party software is to follow the steps you saw on the website.

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.

It’s less complicated than it looks like. The text is just a poorly written mess, full of options (Fedora vs. Ubuntu, repo vs. no repo, stable vs. beta), and they’re explaining how to do this through the terminal alone because the interface that you have might be different from what they expect. And because copy-pasting commands is faster.

Can’t I just download a file and install it? I’m on Ubuntu.

Yes, you can! In fact, the instructions include this option; it’s under “Installing the app without the Mullvad repository”. It’s a bad idea though; then you don’t get automatic updates.

A better way to do this is to tell your system “I want software from this repository”, so each time that they make a new version of the program, yours get updated.

but I have no idea what I’m doing here.

I’ll copy-paste their commands to do so, and explain what each does.

sudo curl -fsSLo /usr/share/keyrings/mullvad-keyring.asc https://repository.mullvad.net/deb/mullvad-keyring.asc
echo "deb [signed-by=/usr/share/keyrings/mullvad-keyring.asc arch=$( dpkg --print-architecture )] https://repository.mullvad.net/deb/stable $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/mullvad.list
sudo apt update
sudo apt install mullvad-vpn

The first command boils down to “download this keyring from the internet”. The keyring is a necessary file to know if you’re actually getting your software from Mullvad instead of PoopySoxHaxxor69. If you wanted, you could do it manually, and then move to the /usr/share/keyrings directory, but… it’s more work, come on.

The second command tells your system that you want software from repository.mullvad.net. I don’t use Ubuntu but there’s probably some GUI to do it for you.

The third command boils down to “hey, Ubuntu, update the list of packages for me”.

The fourth one installs the software.

Chance that your Ubuntu version already supports OpenVPN and wireguard (check your settings -> network). If so, just download wireguard/OpenVPN config files from mullvad: https://mullvad.net/account/openvpn-config?platform=linux

Download the .deb and double click it. https://mullvad.net/en/download/app/deb/latest

People seem to be making this a more difficult job than it needs to be. Yeah I get we’re powerusers but can’t we drop that for 2 minutes while giving advice so a new user can actually get a job done quickly? Windows EXEs don’t automatically update either. Sure it might not be the best way to do it but it’s fast and not confusing. (EDIT: Apparently this specific program actually has it’s own auto updater)

Things take time to learn. Throwing all of the existing knowledge of repo management at a new user at once does not work.

My favorite part of this thread is everyone just saying copy and paste the commands so it will work. Like we should totally get users into the habit of running random commands off the net as root.

The comment section here is a perfect example of why people don’t use Linux

This post is proof that Linux desktop isn’t as good, perfect and polished as everyone says it is. Stop living in the delusion.
