We're tracking this breakage upstream at http://tracker.ceph.com/issues/10893 , "Install failing on RHEL-family machines (due to mixed package sources?)" and downstream at https://bugzilla.redhat.com/1193182 , "ceph has unversioned obsoletes" - Ken _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
