Fedora 32 KDE - Discover

I recently installed Fedora 32 KDE and noticed a couple of problems with Discover.

  • When I try to install more than one flatpak program at the same time, Discover reports the error “Aborted due to an error”. If I install the flatpaks one by one, everything works correctly.
  • I downloaded several .rpm software for Fedora (for example Teamviewer, Chrome, etc.) but when I try to install them automatically with Discover via double click, it always tells me a problem with the GPG key and does not allow me to install anything. From dnfdragora and from cli, on the other hand, everything works correctly.
    I already tried to format and do a fresh install of Fedora but these problems still remains.
    Does anybody else happened to have these problems?
