I don't have any knowledge about this message, though it sounds like
it might be from Gnome Software center. There is more discussion about
this here:

Since you are using kde, it might be that a reboot doesn't trigger the
correct application to update and then turn this message off. You could
try going into a terminal or console and running
dnf update
to see if this would perform the pending updates, and then the next time
you boot, whatever is sending the message might see that they are
no longer pending and remain silent.
How do you do your system updates?
