Download the package again

Apparently it is corrupted in that repo.

Seems its still broken:

sudo rm /var/cache/libdnf5/home_paul4us-b9251e1f4b97dd77/packages/klassy-6.2.breeze6.2.1-10.2.x86_64.rpm

Try to deactivate the

Repository and do make a update again. You might have also to check if you can delete manually the file:
(/var/cache/libdnf5/home_paul4us-b9251e1f4b97dd77/packages/klassy-6.2.breeze6.2.1-10.2.x86_64.rpm)

After having an upgrade without errors, you try to activate the repository again. I think this way it will push the new gpg-key or try an new download.

Figured out that home_paul4us was the theme repo at GitHub - paulmcauley/klassy: Klassy is a highly customizable binary Window Decoration, Application Style and Global Theme plugin for recent versions of the KDE Plasma desktop.
