Hi,
I'm trying to upgrade from 27 -> 28.
Yesterday I was running `sudo dnf system-upgrade download --releasever=28` when I had a
power failure.
After I got power back, I tried to run it again I get the trace below.
I have tried repeating the process again from `sudo dnf upgrade --refresh` and removing
and reinstalling system-upgrade, but I still get the same message.
Any suggestions on how to get round this?
Cheers,
Ewan
