I switched from Windows to #Ubuntu Linux in 2006, and used exclusively Ubuntu until, idunno, maybe four years ago. In all that time, I never had a good experience upgrading from one version to the next. I always had to do a clean install, so after a while I mostly stopped trying upgrading, but still did try one more time somewhere close to the end of that period, I think. Same outcome.
Now I just did my second upgrade of #Nobara Linux, based on Fedora, and it seems to have worked fine! #Linux
The only problem I've noticed so far (I upgraded a few hours ago) is that three finger gestures has stopped working. I know that's important to some, but I never use it. And I saw one other mentioning issues with that after install, so I don't really think it's a problem with upgrading. Though I don't know.
Still, I would not really recommend #Nobara to newbies, though. You should know a little bit about Linux (I only know a little myself) before using this, IMO.
@forteller I upgraded Fedora two versions in one sitting last autumn. Went without a hiccup.
@forteller Fedora has historically been really good about updating to newer releases. Ubuntu has been better the last few releases.
