What happens if you run

echo "10.0" > /etc/dnf/vars/releasever

and try again?

Thanks!

Please note that it will lock the whole OS to 10.0 and you won't be able
to update to 10.1 -- though we'll support 10.0 until 10.2 is out.

Since AlmaLinux 10.1 is out now, you can remove that file and update OS
to 10.1 and receive OS updates.

Will do. I'm still polishing a few things (fixed extras repos today.
non-free repo is left for now). I'll likely do that later tomorrow
night.
