Hello: I finally got the ks_build script finish beatifully with no errors and I have a new comps.xml and header list file. I have (maybe a shortcut a shouldn't have used) put all RPMS in a group called 'All'. In my kickstart file I have entered the following: %packages --resolvedeps @ All Nothing else. Now when anaconda gets to the package resolving stage I get an error window with several anaconda messages, finishing with "KeyError: Base" Any thought on how I could resolve this? Thanks AR
