[Spacewalk-list] Problem installing Spacewalk on CentOS7 (Brand new install)

[Bruce Wainer]

Robert,

Thanks for the attempt at helping, but I've already checked these two xml files. The spacewalk installer had properly set up the <id> entries, and the redhat troubleshooting page I linked in my original thread includes checking the contents of these files also. I believe I have also looked at this particular page as well in the past - I really have looked at almost every google result for relevant search terms on this error.
