hi.. we have a situation with yum/rpm/apt-get where yum/apt-get doesn't seem to work to do a linux OS/FC update. can someone tell us if there's a way to essentially clean the system/rpm db, so we can restart fresh... we'd like to be able to reinstall the correct rpms for yum/fedora-release and essentially do a 'yum -upgrade' and have yum go through the entire process, as if there were no files/rpms already installed on the system.... we can find no information as to how to do this process. we've tried to remove yum, as well as various dirs with no luck.. if we can get to a clean start, we can reinstall the OS over itself, and get a clean OS... thanks -bruce
