After yum clean all -and 500 files less- I got the following when I try to yum update again: [root@dc85d4bc3 leodoc]# yum update Repository dag already added, not adding again Repository freshrpms already added, not adding again Setting up Update Process Setting up Repos Cannot open/read repomd.xml file for repository: core failure: repodata/repomd.xml from core: [Errno 256] No more mirrors to try. Yum was working just fine before the clean all was applied. Did I mess things up? Leopoldo Olmos
