+++ This bug was initially created as a clone of Bug #1179530 +++ Ran into a similar problem with my syslog-ng repo. Looking at the logs at https://copr-be.cloud.fedoraproject.org/results/czanik/syslog-ng36/fedora-21-x86_64/syslog-ng-incubator-0.4.1-3.fc22/root.log I see, that: DEBUG util.py:366: https://copr-be.cloud.fedoraproject.org/results/czanik/syslog-ng36//fedora-21-x86_64/devel/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" Note the "/devel/" in the path. In real life that directory does not exists. So copr can't download repo information and skips dealing with packages from the repo -->> dependencies are not met.
I cloned this as this is different issue and I can confirm it.
Ahh, this is NOTABUG DEBUG util.py:366: https://copr-be.cloud.fedoraproject.org/results/czanik/syslog-ng36//fedora-21-x86_64/devel/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" This is just warning, which is ignored. We pass to mockchain: -a https://copr-be.cloud.fedoraproject.org/results/czanik/syslog-ng36//fedora-21-x86_64/devel/ -a https://copr-be.cloud.fedoraproject.org/results/czanik/syslog-ng36//fedora-21-x86_64/ If you edit your project and check: Disable automatic repository meta data generation then the yum metadata is generated into /devel/ so it is invisible to users, but you can still use it to build your packages. When you uncheck it, then /devel/ is cleared. So if you happen that your build fails, it is because of other reason, search for error further in root.log or build.log.
