Just as an addition: I made an update with kernel excluded and everything went fine. All
the update issues I reported seem to be related to the kernel.
There is on exception: certmonger, issues a message: „No CA with name „certmaster“ found.
By the way, there are a lot of differences in installed packages between the SBC image and
Fedora Server Installation DVD for x86 that are probably not architecture or hardware
specific. For example, the image installs flatpack items that we don't really want on
Fedora Server.
