[Fedora-sparc] yum updates

Just installed Fedora release 12 (Constantine) on a SPARC (v240), but I'm not able to use yum to get updates. Do I need to change or add a repository for yum to work? Thanks, Neil [root@sauron ~]# export http_proxy=http://172.16.XX.11:3128 [root@sauron ~]# yum -v update Config time: 0.135 Yum Version: 3.2.25 Setting up Package Sacks Error: Cannot retrieve repository metadata (repomd.xml) for repository: fedora.
