Hi, I got an error in mock building in my environment for fedora-rawhide from today. Yesterday I could do mock building. My colleague also got same error for another package's mock building today. Is anyone working in the system now? Thanks. Below is for detail. $ mock -r fedora-rawhide-x86_64 rubygem-bundler_ext-0.4.0-3.fc25.src.rpm Run?
