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.

This is one of the hardest walls for people to jump over mentally, from scavenging the internet for binaries to using a package manager.
I think ideally one should understand what they're doing, I think that if you did you would realise it's not hard, just different from what you're used to. Usually you install things using the graphical package manager, of which there are a lot, since I don't know which one you are using nor have I used any of them in a long while, I'll use the terminal as an example (same reason the site uses terminal commands), but all of this is almost assuredly possible via GUI.
To install things you usually do
sudo apt install, this is a huge advantage on Linux, it works similar to your phone in that everything gets updated together but also it installs dependencies separately, which means that instead of having 10 copies of the same library for 10 programs that use it (like on Windows) you get a single one, which is part of the reason binaries are smaller on Linux.The problem with this approach is that some programs are NOT listed there, the only programs there are the ones the maintainers of your distro (Ubuntu in this case) can review and approve. So you can have a lot of different solutions for this:
The first and most obvious for Windows users is to download the .deb from the website and just run that like you would a binary on windows, i.e. double-clicking it, or from the terminal you can run
sudo dpkg -i. This works, but you lose the advantages of a package installed via your package manager, i.e. you would get the same experience as on windows, so it's not ideal.The second way is the one they're describing, essentially you're adding a new repository to the package manager, that the people who wrote the program are maintaining (instead of Ubuntu guys), this is a two step process,
sudo curl -fsSLo /usr/share/keyrings/mullvad-keyring.asc https://repository.mullvad.net/deb/mullvad-keyring.ascthat command is downloading the filehttps://repository.mullvad.net/deb/mullvad-keyring.ascand putting it in/usr/share/keyrings/mullvad-keyring.asc, this is needed because repositories are not trusted by default, that would be a security nightmare, you can do this via GUI if your problem is with the terminal , just download the file and copy it to that location, it's just harder to explain than giving you a command. Then it's adding the repository to the repository list, the command isecho "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.listthat command has a lot to unwrap, in essence it's editing the file/etc/apt/sources.list.d/mullvad.listand writing a line likedeb [signed-by=/usr/share/keyrings/mullvad-keyring.asc arch=amd64] https://repository.mullvad.net/deb/stable focal main"there, but because the guy who wrote this doesn't know your architecture (e.g. amd64) nor your version (e.g. focal) he wrote a command that gets that information from your system, you can instead write the file yourself if you know those. Then install via package manager as normal.There's a third way which is more recent which is install via snap/flatpak which is similar to install via package manager, except you don't add new repos.
There's a fourth way which is manually, usually when you compile stuff you install them manually.
I know it's a lot to take in, but I'm of the opinion that if you understand what's happening it makes things easier.
The problem is that for most users, when their setup is completed they won't need to play with it for a while so after that any time they need to install something new through the terminal it means losing time to find instructions again.
Nothing is learned, to the eyes of a casual users it's just meaningless entries getting copy/pasted and it's information getting repeated again and again and again just with slightly different entries for each program. Meanwhile "how to install a program on Windows" would basically require one page on the whole internet to cover 99% of situations: "Download the install file, double click it, follow the on screen instructions to automatically install the program".
Which is why it's better to understand what you're doing than blindly copying pasting. You won't need to remember these since whatever you want to install if it's not on the repos you'll have to google it same as if you were on Windows.
Also on Windows the steps are: Download the install file, double click it, follow the on screen instructions to automatically install the program, then every week or so go back to the website, check if a new version was released, if so download it and install it again. If the configuration would be destroyed by doing this first, make a backup first, if the new version is not backwards compatible for configuration move the existing configuration changes so that you get the new default after install and can apply your changes afterwards.
That's closer to the truth, and you need to do that weekly for every one of the dozen or hundreds of programs a person has, no wonder people don't update their programs on Windows and become susceptible to lots of exploits over time.
Also, read my option 1, which is what most websites offer you first, i.e. download a .deb and run it which is the equivalent of Windows, with all of its downsides. For example if you go to that website that OP posted and click on downloads you can select Windows, Mac or Linux, and you can download an installer that way and be done with it. But only Linux has a better option that takes a couple more steps but saves you lots of time in the future.
then every week or so go back to the website, check if a new version was released, if so download it and install it againDon't know what kind of program you're running but... No.
Also if you want adoption you need to make your product easy to use and not ask them to become experts at how things work. Do you think all bike riders know how to adjust their derailer or even care to know? No, because people have other things they care about. Same guess 6 for computers, if Linux requires users to understand how to do things manually in the terminal then the "year of the Linux computer" will never happen.
It won't, that's fine. People who don't want to lean anything about computers use iOS and Android now. And that's fine. I never want Linux distros to become like that.
Honestly the more I hear "year of linux will never happen", the more I am convinced it might come. I see ppl being defensive against a new trend
My Linux has updates every week, which means that if I was on Windows to keep everything the same up to date I would need to check every website to see which app released this week, maybe this week Firefox had a new release, maybe next week it's mullvad VPN, and next week is the NVIDIA driver, but if I hadn't checked all of them I would not know which ones have a new release.
Agreed, but also you should have options so that power users can take advantage of it.
Do you think that bikes should not have gears since most people don't know how they work? No, because even if you don't understand the mechanics you can understand the general terms, and even if you don't understand gears you can just not use them, same as a package manager. Options is always better.
It doesn't require it, you're ignoring the fact that OP could have just clicked download and download an installer same as he would on Windows. But if you can use the terminal and understand package managers you can use Linux in a way that Windows is impossible, if you can't you can still use Linux in the same way you would windows with all of the sales downsides.
It doesn't require it but it is often easier. It's also alien when you're new.
Just as an addendum to your answer. In the command writing to
mullvad.listthe| sudo tee /etc/apt/sources.list.d/mullvad.listis using two helpful linux utilities to modify the command. The first is the|which is called a pipe and connects the text output of one program to the text input of another. The pipe is connecting the output of echo which simply prints a string, in this case composed of the outputs of several other commands to the programtee. Tee which is given admin privileges by thesudotakes an input stream and splits it between two files. In this case those aremullvad.listand since no other was providedstdoutthe output pipeline of the terminal running the command.EDIT:
In the interest of further completeness. Another utility used in those commands is the command substitution operator of
sh. So when the terminal is interpretting text$(some command)gets substituted out for the text output by the command in the parentheses. It is another common way of connecting commands on the shell to allow for more flexible and powerful commands.
