Description of problem: PackageKit is telling that there are 1534 updates available. This number is the same as the amount of packages that are installed. Runnimg pkcon update gives - as can be expected - 1534 times '... is already installed'. I've updated my system dnf which works as expected. B.t.w. I'm using KDE spin.
