I had the same thing happen on an F22->F23 upgrade. Essentially you have to figure out
which F24 packages got installed, and remove them by hand. 😖
Then you can resume the upgrade. Make sure the fedora-release-24 package is already
installed before you continue!

I have a machine where I tried to do a system-upgrade from F23 to F24.
The download portion worked fine but after the reboot, the upgrade
process aborted. I'd like to know why, but first I need to clean up the
mess so I can try it again. Right now I have 4782 total packages
installed including 1490 fc24 packages. I haven't checked all of them
but it appears that all are paired with the same fc23 package.
Trying to repeat the download step, I get this result.
# dnf --allowerasing -y system-upgrade download --releasever 24

Dependencies resolved.
Error: The operation would result in removing the following protected
packages: systemd.
Evidently, there are two systemd packages installed:
# rpm -q systemd
systemd-222-14.fc23.x86_64
systemd-229-13.fc24.x86_64
No new kernel was installed and the machine is running fine as F23. But
I'd like to get it upgraded...
I tried using "dnf history rollback" but that didn't work, reporting
"A
transaction cannot be undone". Since dnf won't erase the extra stuff, I
can probably do it with something like, "rpm erase --force $(rpm
-qa|grep fc24)" but that seems iffy. Better suggestions are very welcome.
