uBlue Bluefin or Aurora. Tested and approved. I moved my dad on Bluefin one year ago, no issues, it just works for his use case (90% of the time in a browser, light photo editing in Krita, some text editing). No maintenance, no updates, no actual knowledge needed as a daily user, just a single reboot once a week to boot the freshest system image.
And more importantly, it keeps on working despite his talent for fucking up every single piece of software he lays his hands on.
You’ve never heard of atomic/immutable distros? You’re part of the lucky 10,000 ;)
Bluefin, Aurora and their much more popular sister Bazzite are part of the universalBlue project: a delivery pipeline that lets anyone build their own, maintenance free atomic distro.
All uBlue projects are 100% based on Fedora Silverblue, itself an atomic distro based on Fedora. Which means that uBlue projects get automatic weekly upgrades just like Silverblue.
For people not familiar with Linux, and people who don’t want to spend any time maintaining their OS (HTPC, gaming rig etc), it’s amazing.
