If you’re really wanna learn, I recommend the arcolinux way, they start simple and take you on a tour. Just arcolinux.com. if you want something, that simply works without any effort: Ubuntu, mint, or any other recommendations here. I myself started with Suse many years ago, and that was a mess, to be honest. But: it forced me to learn. And we are best, when we are forced to learn. Humans are hardwired that way, I think.
