Yum not updating

[Dotan Cohen]

I just tried twice to yum update, but I get this error:

[root at localhost ~]# yum -y update
Setting up Update Process
Setting up repositories
Cannot open/read repomd.xml file for repository: livna
failure: repodata/repomd.xml from livna: [Errno 256] No more mirrors to try.
Error: failure: repodata/repomd.xml from livna: [Errno 256] No more
mirrors to try.

Must I just comment-out Livna? I want to be sure that I update all
that is necessary. What can I enable to replace Livna?

Thanks in advance.
