buildroot repos

For two days now I've been unsuccessfully trying to build a Kodi package update. DEBUG util.py:257: http://buildsys.rpmfusion.org/plague-results/fedora-21-rpmfusion_free/ffm...: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404" DEBUG util.py:257: Trying other mirror. DEBUG util.py:257: http://buildsys.rpmfusion.org/plague-results/fedora-21-rpmfusion_free/ffm...: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404" DEBUG util.py:257: Trying other mirror.

Can someone who has the power to look at the repos fix this? Thanks, Michael
