I have problem with redhat-config-packages and yum on my FC1. it looks like it is a problem with the python and libxml2. I have upgraded my box from Red Hat linux 9 to Fedora Core 1. I am getting the following error whenever i launch yum or redhat-config-pcakages import libxml2mod ImportError: /usr/lib/python2.2/site-packages/libxml2mod.so: undefined symbol: xmlTextReaderIsValid I am unable to use these tools. command line rpm works fine though. Are there any issues reported while upgrading from RHL to fedora ?
