“I have no idea what I’m doing here” <- Happens in the beginning. How about you start by trying to know what exactly you are doing? Let me give you a fasttrack…

1. The first command you get in the instructions is curl. It is generally used to download stuff from a networked server.

   1.1. To understand the -fsSLo in the command, I strongly advise you to check out the manual of curl using man curl in a terminal.

2. The second command in the instructions is echo “something” | sudo tee some/file

   2.1 Here you see 3 commands echo , sudo and tee. 2.1.1 Again, you can use man command-name to check the manual pages for these commands 2.2 There is a | symbol over here. It is called the “pipe symbol”, which is what you can use to search for it. It is usually difficult to search for the symbol itself and I haven’t found a man page for it, but open man bash and look for “Pipelines” and you’ll know what it is about. Use Link, Link and Link to help yourself understand this.

3. The commands in “Install the package” use the apt program. This is a https://en.wikipedia.org/wiki/Package_managerhttps://en.wikipedia.org/wiki/Package_manager. Its job is to read package information that package developers have made and try to not let the system become unusable.

   • e.g. If you have a program called Xorg from 5 years ago, and a program called mesa from 5 years ago and Xorg depends upon mesa to work. Here, if you replace your mesa with a new, recent mesa yourself, there is a good chance Xorg will not work. The Package Manager prevents that from happening.

4. The gist of what the instructions are making you do is, telling the Package Manager that there is another place from where you want it to look for packages.

Don’t think too badly of people dissing you in the comments. They are tired and fed up of help vampires. Hopefully, you can try not to become one.

• Try and build your own process of understanding the commands you see on the internet before entering them into the terminal.
• The comments telling you to just follow the instructions, are coming from the perspective that you don’t have the patience and determination to understand them yourself, which, a lot of people don’t. I will leave it upto you to determine which one you decide to be. It is, however, a bad idea to follow instructions on any website, just because it “seems legit”. You can’t really say you “trust” the site until you have the ability to find out for yourself whether you want to trust it.
