The webkitgtk package will be removed from rawhide after Fedora 26 is branched due to the high number of unfixed security vulnerabilities. You must remove this dependency or sparkleshare will not be present in Fedora 27. Please refer to [1] for a FAQ on this matter and be advised that for some packages this may require a substantial amount of work. Note the dependency is via webkit-sharp.
