I would then go look for it in Nobara package manager and see if it needs updating or not and see what version it is running.
Another thing I would check is what version is standard in the supported distros. I’m guessing that list includes Fedora and Ubuntu and/or Debian. If the version they expect is different from what you have then we need a way to make the right version available. I’m not sure what is the best answer but I have a few ideas that I would try if it were me.
Man I tell you, apps that have one off install approaches like this are so annoying. I’ve run into this a few times. It just leaves me feeling dirty. Why can’t they just distribute an AppImage or rpm for Pete’s sake?
