This build (of copr-frontend) failed on all chroots: https://copr.fedorainfracloud.org/coprs/g/copr/copr-dev/build/166544/ The next build on the same sources executed about 20 minutes later succeeded: https://copr.fedorainfracloud.org/coprs/g/copr/copr-dev/build/166549/ (it was run only on chroot 'fedora-23-x86_64' though) The only (for me) noticeable error in the logs (mockhain.log) for the first build is: [2016-03-08 12:12:32,462][ ERROR][PID:23074] builder.build error building pkg `copr-frontend`: BuildError: rc 2 not in success_codes; return code: 2; stdout: starting logfile: None
