yum error

[BB Cao]

Hi All,

I was trying to use yum, so you can imagine how fresh
yum  sounds. I got the following:

yum update mplayer
Repository updates-released already added, not adding
again
Repository base already added, not adding again
Setting up Update Process
Setting up Repo:  dries
repomd.xml                100%
|=========================|  951 B    00:00
Setting up Repo:  updates-released
repomd.xml                100%
|=========================|  951 B    00:00
Setting up Repo:  livna-stable
Cannot open/read repomd.xml file for repository:
livna-stable
failure: repodata/repomd.xml from livna-stable: [Errno
256] No more mirrors to try.

How do I fix it? I guess I need keep update yum
somehow ,if so, how? Thanks.

Best,
 BB Cao
