Lately, the latest version of Cosmic has been giving me quite a few problems, so I had to switch to Fedora 43, which hasn’t given me any trouble.
The thing is, I notice quite a few differences in terms of the maturity of the system updates; it seems to me that Fedora 44 Cosmic is still in the testing branch, which is a clear difference compared to Silverblue or Kinoite.
I don’t mean to disparage the maintainers; I know they’re putting a lot of effort into keeping this running. That’s why I’d like to know when I should or shouldn’t update in the future.
I believe that cosmic is still a spin, what means it is not blocking when we do upgrade. So it can be that on the release date not everything is ready. The desktop with blocker status are KDE & Workstation.
However Beta testing, reporting and upgrade short after new release helps to debug and make it “more ready” when releasing a new version.
I don’t think F44 Cosmic is literally on a testing branch - it seems to use the 1.0 official release of Cosmic.
If you’re comparing to Silverblue or Kinoite though, bear in mind the different maturities of the upstream projects. GNOME and KDE are decades-old projects, whereas Cosmic 1.0 was released only 6 months ago after a couple of years of public alphas and betas.
