It's back in the original state, I just had to force install a dnf
version that was compatible with python3 3.5 ABI. The problem is that
it won't update to python3 3.6 ABI from there. I'll have to do some
manual manipulations to get there.
On a related note, I recall a discussion somewhere on the Fedora
mailing lists, about doing an LVM snapshot of rootfs prior to
upgrading as an easy way to roll back.
I think I remember reading that. And, I think I've seen dnf taking a
snapshot before updating if the snapshot plugin is installed and
enabled.
