Upgrade f37 → f39 not working

I’m after some help with doing this update - I’ve used both the GUI and dnf, the update seems to go successfully, but then the computer boots back into 37.

Try following this instruction:
Upgrading Fedora Linux Using DNF System Plugin :: Fedora Docs

If the issue persists, check the output:

hostnamectl status
dnf config-manager --dump-variables
dnf repolist
dnf system-upgrade log
dnf repoquery --duplicates
dnf repoquery --unsatisfied
dnf repoquery --extras
rpm -q -a fedora\*
