I bet the others already gave a lot of good advice, but there is one thing I wand to emphasize. The way in which you install software matters more on Linux than on any other operating system. You are meant to install it through your distros package manager, which you will most likely use through the software management GUI of your distro. Do not download any executables from websites directly, unless you are absolutely sure that:
- They are made to work on your distro
- They come from a trustworthy source
- You have complete and up to date instructions on how to install them
Sometimes you might need to add additional repositories to your package manager, the same rules apply there. You might also run into things called Flatpaks and Snaps, these are universal package formats and another great option for installing software. Flatpaks work out of the box in a lot of distros. Number one rule there is to stick to things that are marked as verified, unless you have a good reason to trust them. These universal formats might be integrated in the GUI software manager too, this varies across distros.
If you follow those rules and keep your system updated, I don’t expect you will have much trouble with Linux.
