Reported a bug report for koji
It’s greatly annoying that I am not able to do koji scratch builds or fedpkg builds. I had discussion with nirik at #fedora-admin. He asked me to show him the outputs of a couple of commands. I updated to koji 1.6. Still, the problem is persistent. I guess, it is not actually a bug, otherwise others would have surely reported. I think it is some small configuration issue that is being overlooked....
