Your package trickle failed to build from source in current F28. https://koji.fedoraproject.org/koji/taskinfo?taskID=24900662 For details on mass rebuild see https://fedoraproject.org/wiki/Fedora_28_Mass_Rebuild
This needs adjustment for https://fedoraproject.org/wiki/Changes/SunRPCRemoval
For now, I add a workaround.
