I just came across something: [medieval@chaucer ~]$ yum grouplist Setting up Group Process Setting up repositories Error: Caching enabled but no local cache of //var/cache/yum/base/comps.xml from base It seems that if you run yum as a non-root user then yum runs from cache and hence it cannot grab the comps.xml file. That's fine since it needs access to write to /var/cache/yum, but shouldn't there be an error message stating that you need to be root like there is when you try to update/install/remove? Also, I noticed that there is no mention of the 'hidden' option to 'list' in the man page. Bob -- Bob Kashani http://www.ocf.berkeley.edu/~bobk/garnome
