perfSONAR User Q&A and Other Discussion

[Ed Brown <>]

There are no comps.xml or comps.xml.gz file in the repodata directory in 
the 3.5 and 3.5.1 isos.  They do exist in the 3.4 and 3.4.2 isos.  In my 
experience building install images, the error message below and the lack 
of this file indicate that the repo was not created with the -g flag to 
createrepo and the original comps file from the CentOS distro as the 
parameter.  I thought the comp files were needed to be able to reference 
package groups during the install.  Are they not needed anymore, or 
could the iso need to be rebuilt?
