I replaced Manjaro with an easily reinstalled instance of Endeavour OS. As it did before, it’s behaving well. It did have two brief difficulties this year: one was a brief problem with the most current kernel; the second was a brief issue with the yay package tool. Both issues were resolved within less than 48 hours, probably considerably less time.
Endeavour OS is arguably the best Arch Linux derivative available, with Cachy OS a close alternative. I don’t get why anyone uses Manjaro; I’ve had nothing but problems with it every time I try it out. Supposed to be more stable recently; that was not my experience at all, whereas either Endeavour OS or Cachy OS are worth keeping.
