I used unraid last year, excellent experience learning how to use docker + vm in a user-friendly interface.
Now I use debian (installed via debootstrap) headless (docker only).

Thanks !

No, I don’t, thank you very much :D!

I have the impression that everything is in English, do you know of anything similar that offers other languages? My father doesn’t speak English unfortunately

It all started with my father, who dreamed of re-watching films from his childhood. As it was difficult (impossible) to find them in the shops, I used the alternative method. It all started with collecting old films from his era. For my part, ever since I was a child, I’ve had this “little voice in my head” telling me "what would happen if one day the suppliers of music, films, books… disappeared (because of politics, war, the end of sales… or whatever). Since then, I’ve digitally preserved everything I can (I only keep things that are hard to find, useful or that I like). And… mainly because I love technology and discovering all the things people can build with their keyboards.
