### Fedora 26 -> 27 Error

Hello community,

When i try to upgrade i get this unpleasant error:

Error:
Problem 1: package ceph-devel-compat-1:10.2.7-2.fc26.x86_64 requires libcephfs-devel = 1:10.2.7-2.fc26, but none of the providers can be installed
- libcephfs-devel-1:10.2.7-2.fc26.x86_64 does not belong to a distupgrade repository
- problem with installed package ceph-devel-compat-1:10.2.7-2.fc26.x86_64


I have both of mentioned packages above installed in my system. What is the actual problem here?

Just point me to a direction, so i can try to fix it please.
