I had today a machine (a VM with only 4G of memory) where an upgrade
with "dnf distro-sync" failed with result 'oom-kill' (no time to
investigate the precise reason of that).

There was a lot of duplicate packages, including protected packages
like dnf and systemd.

dnf was still pointing to dnf4 (through /usr/bin/dnf-3).

I managed to repair with:

- dnf --setopt=keepcache=yes --setopt=protected_packages= \
      remove --duplicates > FILE < /dev/null

Look then carefully at the list of packages to reinstall, then ran
    it in real:

- nohup dnf -y --setopt=keepcache=yes --setopt=protected_packages= \
      remove --duplicates

I finished then the upgrade with: dnf -y distro-sync

I saw that dnf5 has an issue to provide "remove --duplicates":
