This is the end of the output of the second command:

Download complete! Use ‘dnf system-upgrade reboot’ to start the upgrade.
Then I have restarted the system as mentioned:
sudo dnf system-upgrade reboot
The following is then happening:
The computer restart
The Fedora logo is displayed for a few seconds
The computer restart again
The Fedora logo is again displayed
Login prompt, but I am still in Fedora 31
I have made some research and I’ve found this topic on this discourse, but nothing on it helped:
Somewhere else, I also discovered the systemd unit dnf-system-upgrade.service which I believe is started when a upgrade is supposed to be executed.
I have found some weird errors in the output:
While that seems to have worked, I wonder why you are staying 2 full versions behind the one (F34) that is being replaced in a couple months. F32 is past EOL and no longer getting support. The same will be true of F33 when F35 is released.
System upgrade is only officially supported and tested over 2 releases at most (e.g. from 32 to 34 ). If you need to upgrade over more releases, it is recommended to do it in several smaller steps (read more).
As I had already troubles doing the first upgrade, I decided doing one upgrade at the time until my system is back to a supported version. It also allows me to check if everything seems to be working before going to the next release.
