yum install trinity-desktop gets following errors: ......................... * trinity-r14: mirror.ppa.trinitydesktop.org * trinity-r14-noarch: mirror.ppa.trinitydesktop.org trinity-r14 | 3.0 kB 00:00:00 trinity-r14-noarch | 3.0 kB 00:00:00 trinity-r14-noarch/primary_db FAILED http://mirror.ppa.trinitydesktop.org/trinity/rpm/el7/trinity-r14/RPMS/noarc…: [Errno 14] HTTP Error 404 - Not Found Trying other mirror. ............................ http://tde-mirror.yosemite.net/trinity/rpm/el7/trinity-r14/RPMS/x86_64/repo…: [Errno 14] HTTP Error 404 - Not Found Trying other mirror.
