Description of problem: The NFS kioslave in kio-extras uses the Sun RPC interfaces from glibc, which have been removed in Rawhide: https://fedoraproject.org/wiki/Changes/SunRPCRemoval Instead, you have to: 1. add: BuildRequires: libtirpc-devel and 2. apply this patch: https://github.com/cygwinports/kf5-kio-extras/blob/master/16.08.3-nfs-libtirpc.patch You may or may not want to conditionalize this based on 0%{?fedora}. (libtirpc should in principle work everywhere.) Version-Release number of selected component (if applicable): kio-extras-17.12.0-1.fc28
