Developers and contributors reported that cooker update now it’s possible again.
The proper command is
$ sudo dnf clean all ; dnf clean all ; dnf repolist ; sudo dnf --refresh --allowerasing distro-sync
Please disable additional repositories before proceeding with the upgrade.
You can enable them again later.
The kernel has changed its name, users will have to manually type the install command.
Now the default in cooker is clang
$ sudo dnf install kernel-desktop
If you prefer the gcc compiled kernel
$ sudo dnf install kernel-desktop-gcc
