Your snark at my comments is completely unwarranted.

I really shouldn't have to explain what follows. But I will.

Installing any dev tooling that is third party is done on the command line. Look up the instructions for installing Node LTS on Debian, or .NET, or Golang. You need to use the command line. Even on easier to use Distros they have the same procedure. Depending on the tooling you may need to set additional environment variables which are normally done in your .bashrc or similar.

What normally happens is people blindly copy and paste things into the terminal and don't read the documentation. This has been a problem on Linux since before Ubuntu was released. This isn't just limited to newbies either.

The state of GUIs BTW isn't great. Many of them look nice, and work reasonably well most of the time, *until they don't* e.g. If I double click a deb to install it, sometimes it will install. Other times it won't. So I don't even bother anymore and just use dpkg/apt. BTW it isn't any better with other distros. So I have to drop to the command line to fix the issue anyway.

So at some point you will need to learn bash, learn to read the man pages, and manually edit configuration file. It is unavoidable on Linux.
