Fedora 32 : Upgrade from Fedora 31 to the new Fedora 32.

Today I managed to upgrade to Fedora 32.
After some time I started the system and used the tutorial from here.
I also used the following Linux commands:
#sudo dnf distro-sync --allowerasing
#dnf reinstall xorg-\* mesa\* libglvnd\*
In the following image, you can see the new upgrade works very well with my Cinnamon desktop environment.
