You spend years auto-learning.

What can be the first steps

You Google "how to xyz" changing "xyz" to stuff you want to learn and you learn.

Start with how linux works. Install it and play with it. Expect a lot of command line typing.

I’ll work on it , thanks !!

If you go the Ubuntu desktop route, try running it without the GUI(Graphical User Interface) after you get used to some of the syntax etc. Maybe Install and configure a few apps etc via in the CLI (Command Line Interface)
