As I mentioned somewhere, I still have both packageKit and dnfdragora
installed.
There are times when the packageKit updates icon appears on my systray
telling me a number of updates
are available.
But, when I run "dnf --refresh upgrade" I am told "Nothing to do".
I just try again later in the day.
I usually ignore the "nothing to do"
situation as well and just issue
the command again the next time I'm ready to put on updates again. It is
a bit disconcerting though when Discover reports there being, in my case
638MB of Fedora System Updates as opposed to application updates, right
from the first boot of F34 after a fresh install, and that calculation
of how many updates are available never changes irrespective of how many
updates are applied by dnf and how often. I've had F34 installed in the
vm for probably around 6 months, and Discover has never stopped
reporting 638MB of System Updates until I actually put them on.
