Is Fedora KDE Limited in Software Support Compared to Ubuntu?

Debian-based distros generally have a wider range of official software packages available. On RPM-based systems like Fedora, you might need to lean more on unofficial packages or use something like Snaps or Flatpaks to get what you need. So yeah, it's a bit of a transition, but using Flatpaks is becoming more common and could help with your software issues.

I've had good experiences with both Kubuntu (Debian-based) and openSUSE Tumbleweed (RPM-based). For me, Tumbleweed has been great because I rarely run into issues finding apps. You might want to give Kubuntu a shot if you're looking for something that receives regular updates like Fedora—it updates every six months too.

Historically, Debian and Ubuntu have had the lead in packaged software. These days, using Flatpak can often fill in those gaps. I’ve even converted .deb packages to .rpm in the past. Regardless, Fedora is catching up, and you might find that most of your needs can be satisfied there now.

If you’re looking for newer software versions, you could consider Ubuntu 25 (the non-LTS version) or Debian Testing/Unstable. Also, I found that you can sometimes manually extract and install .deb packages, though that's not always ideal. As for Parsec, it seems like you might need to rely on Flatpak for that on Fedora since there's no direct package.

There’s a Parsec Flatpak available on Flathub! Have you checked it out? Just a heads-up, though: some people mention you can’t host with it. Still worth giving it a try!
