I have a question to your request: Do you have in /etc/dnf/dnf.conf following line: installonly_limit=3 Did you made ``dnf upgrade --fresh`` before system-upgrade attempt? Do you run the newest kernel on your system? If some of the answers were no it could be a reason why you have the issue. If you will upgrade running kernel the replacement should take place during the reboot, therefore theoretically it should be save. On other hand any time when you perform the system-upgrade you have to consider a risk of malfunction of your upgraded system. Therefore back-up or snapshot could be handy.
