Best teacher I had was breaking things by installing everything under the sun then trying to fix it. But its time consuming.

I would say go at it yourself, you’ll learn along the way, same as you did with windows. For tips, its hard to say, see if you can get your hands on Sander van Vugt - linux fundamentals. I watched it a few years into my linux journey and it schooled my ass still.

I haven’t heard that one before, gonna use it :D

If you haven’t tried dietpi on your sbc’s, try it, it is much better than the usual default, its glorious.
