When I attempt "yum update", I get the following error message. Using my newly updated FC4 from FC3. I appreciate help or a yum.conf file that works in FC4: Cannot open/read repomd.xml file for repository: livna-stable failure: repodata/repomd.xml from livna-stable: [Errno 256] No more mirrors to try.
