dnf problem: cannot install both - conflicting requests

edit

Fedora 27 Gnome 3.26.2
4.14.14-300.fc27.x86_64

I was updating the system when there was a power outage, when I tried to update again I get these errors:

Running transaction check
Transaction check succeeded.
Running transaction test
The downloaded packages were saved in cache until the next successful transaction.
You can remove cached packages by executing 'dnf clean packages'.
Error: Transaction check error:
