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?

Thanks, Thomas

[pi@raspi ~]$ sudo dnf -y system-upgrade clean
