I got the exact same problem (same packages) and reinstalled the packages with DNF. The kernel packages are still not installing, should they also be installed with dnf?
sudo-dom0-update --clean --verbose prints these warnings: Unknown configuration value: failovermethod=priority in /var/lib/qubes/dom0-updates/etc/yum.repos.d/fedora.repo; Configuration: OptionBinding with id "failovermethod" does not exist repeated many times. Then an error message: Downloading Successful, but checksum doesn't match This all started after upgrading the template for the updateVM (sys-firewall) from Fedora 28 to Fedora 29 and shortly thereafter to 30. sorry if not posting correctly, i just joined the list -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
