Hello everyone, I am a new koji user. These days I was setting up koji environment on redhat6, using koji 1.6.0 and mock 1.1.12. After that, I tried to run koji build system on my own server. Then I encountered a problem about mock. when I run the build command, the build system did not work correctly, and exited with the following information:

BuildrootError: could not init mock buildroot, mock exited with status 20.

After that, I checked the build log, and find it failed after sending this command to yum:

¡°/usr/bin/yum ¨Cinstallroot  /home/fedora/mock/build0.1-build-43-28/root/ groupinstall build ¡±

The error information is:

Warning: Group build does not have any packages.

The yum.conf directory was :

/home/fedora/mock/build0.1-build-42-28/root/etc/yum/yum.conf

And the repodata directory was:

/home/fedora/koji/repos/build0.1-build/28/x86_64/repodata

I checked the comps.xml and the repomd.xml in repodata£¬and could not find any problem.

 

When I use yum to run this command :

/usr/bin/yum ¨Cinstallroot  /home/fedora/mock/build0.1-build-43-28/root/ groupinstall build

It was the same error.

But when I use other directories as the installroot, this error didn¡¯t happen. Did someone know why did this happen?

 

 

Root.log:
