I want to start using Linux but I am not sure how to get started. I just want to set it up a server for my mvies and such. Maybe I am starting too big. I don’t know. I use to think I was moderately good at computers but I feel left behind. Just looking fro advice on my first build.
Find an old laptop. Install TrueNAS community edition. Read about containerized server apps. There are alternatives like Mint if you still want to have and learn a desktop experience. Read online blogs. Ask here if any further questions arise. Avoid dual booting until you are comfortable with installing an OS and handling grub.
