Dear All, to upgrade a Raspberry 3 I executed this commands
sudo dnf -y upgrade --refresh sudo dnf -y install dnf-plugin-system-upgrade sudo dnf -y system-upgrade download --releasever=30 sudo dnf -y system-upgrade reboot
after the reboot dnf fails. Is anyone else having the problem?
I used the same commands to upgrade a Raspberry Pi 3 from F29 to F30, and do not see your problem. Dnf works as expected in F30 for "dnf system-upgrade clean", "dnf list upgrades", and "dnf upgrade".
