Hello I have been having issues with spacewalk and Scientific Linux 6.4 and 6 rolling repos after investigation I found 2 errors first " Repo http://ftp.scientificlinux.org/linux/scientific/6.4/x86_64/os/ has comps file comps-sl6-x86_64.xml.gz. ERROR: Not a gzipped file " The second is spacewalk 1.8 doesn't handle the error gracefully but version 1.9 does. note version 1.8 does not produce the "ERROR: Not a gzipped file" instead it does a trace back about an unknown error code. Ive checked http://ftp.scientificlinux.org/linux/scientific/6.4/x86_64/os/repodata/comps-sl6-x86_64.xml.gzand been able to confirm that indeed it is not gziped this should be corrected in whatever script is generating it. Thank You Paul Robert Marino
