Giving you a heads up as a Onyx Boox Nova 3 owner. These devices are poorly supported. You’d get maybe a year of “updates”, meaning the bundled apps are updated. But after that you are on your own.

It’s a brilliant e-reader don’t get me wrong, and I’ll take it over a Kobo or a Kindle any day. But go in assuming that you’d want to keep it offline.

I too install Linux Mint, though Fedora Silverblue and Kinote is another good alternative.

I am doing my part 🫡!
