I have been using Fedora since 23 and usually system-upgrades have gone pretty well. I ran the usual upgrade sequence:
dnf update dnf system-upgrade download --refresh --releasever=30 --allowerasing dnf system-upgrade reboot
The system reboots, but I still see the f29 kernel. It get to a certain run-level then shuts down automatically and reboots. Still only seeing f29 kernel and it reboots as before the Fed29. No change.
I do not see the usual “this may take some time …” message and having gone through this loop four times , I do not see any errors or failure posted on the screen.
Presumably there is some log file I can look at to see what when silently wrong.
How can I diagnose the problem?
