everything is a file lol, unlike on Windows where a lot of things are GUI based:

• Want to change your grub font size? Heres a file.
• Your python gives dependencies errors? Well, because the libraries (aka files) are in a different directory.
• want to change your password and username? Heres a file to change …so on and so forth

On Linux you have a lot of power, can use sudo to make changes to a file. If you know what youre doing, great. If you dont, system can break. Even without sudo, a misplace / mistype of files in the /home directory can cause weird stuff.

So TLDR is: be careful when make changes to files on Linux. Dont listen to stranger on forum who gives out command to paste and run. Do your research what the command does.

The biggest “Linux” skill would be package management. It is one of the biggest differences.

Most of the rest of the advice here stems from desktop environment choice.

DO NOT download and install random programs from the internet. Not a deb/rpm file, not an elf binary, not an install script, nothing. Use your package manager or desktop environment’s app store. At most use flatpak or snap packages.

Linux gets its reputation for not getting malware from the same place Mac does: It has a managed app repository where you get all your software from. Difference is Mac doesn’t let you install arbitrary programs at all, while Linux expects you to know better than to do that. Someone who doesn’t know what they’re doing downloading Linux programs from random websites will inevitably hit one of the super rare Linux malware in the wild.

Even ignoring security issues, running an install script even from a reputable open source project’s website can open you up to package dependency hell. And if you ever need to upgrade or modify it, you’re in for a rough time because none of the existing tools built into your distro will help you. It’s even worse than Windows when this happens because Windows at least expects for things like this to happen (because everything comes in its own installer and handles updates separately) and has UX elements to help non tech savvy users deal with their mess of apps, Linux expects anyone bypassing the normal package manager to know what they’re doing and if you don’t, it won’t be a good day for you.

One thing that many guides tend to skip is how to install software. People coming from Windows might try to install software the “Windows way” by going to the website and downloading them. That is just likely to cause pain and suffering for a number of reasons.

Instead, every beginner friendly distro has its own flavour of software centre that users should be encouraged to use instead. Maybe even include a link to flathub in the guide or something.

I set up Mint for a non-techy relative on their old desktop.

• Their use-case is almost entirely web browser, so there was no need to cover installing programs. Click the same browser icon and it should behave basically the same way.
• No need to explain the terminal beyond “this is where you can type advanced commands, you don’t need to worry about it”.
• If there’s an error message, read it and try to understand what it’s actually saying rather than just dismissing it. Do a web search if you’re feeling confident, send me a photo of the screen if you’re not.
• Explain how to install updates (or just configure automatic backups and updates for them).
• Explain when and why the computer will ask for a password (e.g. login and updates) and how that password is for the computer, not for their email or whatever.
• Explain the basics of folders. This is your home directory, here’s where downloads go, here’s how to create a folder and drag your files into it.
• Tell them not to panic. I’ve seen a lot of older people terrified of pressing the wrong button, make sure they know how to understand what they’re doing and undo their mistakes.
• Be patient!

Backing up a copy of that config file, before editing it.

If you brick or break anything, rolling back to a working-state is much easier.

You can manually cp a 2nd version of the files, or there are tools to automatically backup for you.

Trusted sources, only.

Same as Windows, Android: sideloading (tarballs, flatpaks, snaps whatever) is a no-no.

Like bash curl install.sh bad

I think the biggest fundamental concept for any computer regardless of operating system is filesystem hierarchy. The concept of nested folders is core to using a personal computer, but for the last two decades UI/X teams have done everything in their power to obscure and abstract it away. Many younger people conceptualize the storage on their device as just an amorphous blob that apps manage autonomously. Windows is starting to go this way as well with OneDrive being sold as the way to manage all your data, but on Linux the file system is still king.

Your mom is presumably old enough to have some experience with desktop PCs, so hopefully that basic hurdle is already cleared. And honestly once someone is at that level of base competence, along with basic interface concepts like how to use a mouse and keyboard, clicking on icons, use of a web browser etc, with the right distro you really don’t need to explain much else. There might be a few quirks of the UI to explain depending on what you choose, but most of that can be handled by just watching them use the computer for a bit, and/or asking them to give you a list of questions and annoyances after they use it for a few days.

The biggest difference is one that most “I just want it to work” users will actually love, and that’s relearning how to install software. Having one central location to install verified software from is a change from the wild west of downloading installers from the internet, but it shouldn’t be a difficult transition. Most people these days don’t even install software beyond maybe Zoom, so you can probably get away with just installing any third party software they need in the initial setup.

I recommend an immutable distro like Fedora Silverblue, at least if a) you’re setting it up and are reasonably technical, and b) you don’t want to go over and help them fix stuff often. I set my mom’s laptop up with it 4+ years ago and she’s only had one problem since then.

I find that one of the biggest differences is the file ownership/group design, and the non admin user. Sure, it might not come up in a straightforward manner, but it will.

Why do I need to put in a password all the time? How come I can’t just move this file to another drive?

This might be too “advanced” for what you’re looking for, but I think even basic usage comes across this.

The bottom level of your file system is /, not C:, and other drives or partitions you have will be represented in subfolders like mnt or something.

Everything is represented as a file, even things that are not strictly speaking a file on your primary hard drive.

The part that you interact with the most, your graphical user interface, has a particular name, like gnome, kde, xfce, icewm, etc.

When you have to open a terminal, you might be interacting with different shells as well, but it will usually be bash.

Always install from the repos unless your nerdy friend who helped you get set up says it’s okay to download this or that particular app.

Maybe include a bit about how to run regular backups automatically.

And also list out different alternative programs relative to what they might be used to in a Microsoft environment.

That it is another OS. It’s not Windows.

This thread is largely just basic computer skills advice that is necessary on Windows and Mac as well. (And that is great!)

So I’ll add the ones we skipped that have nothing to do with OS at all, but are the usual issues for new PC users:

• Give a quick overview of what the mouse is for.
• Talk about or just disable the CAPSLOCK key.
• Show them where to find and how to read the “do I have Internet?” icon (usually in the lower right, regardless of OS)
• (If not a laptop) Teach them that the monitor and the PC have separate power buttons. Maybe leave a sign out that says “Push both buttons to turn on.”

And as others have said:

• Show them how to search for and add software using the software center, (rather than download from random websites)

su/sudo -Why you will need to use it and how not to use it.

-I still don’t think it’s wise to rely on the various stores like Discover or Pop!_Shop to do basic updates as they are bloated and slow to an alarming rate while running.

Hard to summarize, because it differs so much from person to person.

I installed Linux on my parent’s computer. They don’t need to know anything about Linux, because everything they use is identical to their old Windows PC. They click the icon for Chrome to open the browser. They Click the icon for LibreOffice to type up a “Word” doc and print it by clicking “file > print”

As far as they’re concerned, they are still using Windows.

For a gamer, they will need to know a little about Proton, possibly Lutris and the Hero launcher. They might need to know about installing nVidia drivers or tweaking a few things in the Steam launch options to get games to run better.

It’s tough to know exactly what a new Linux user will “need” to know in order to use Linux.
