I installed Centos 5.4 on a PC server.
I SSH to it and try to use yum to update the system.
But, always give me the error as below
[root@10 ~]# yum update Repository base already added, not adding again Setting up Repos http://mirror.centos.org/centos/4/up...ta/repomd.xml: [Errno 4] IOError: Trying other mirror. Cannot open/read repomd.xml file for repository: update failure: repodata/repomd.xml from update: [Errno 256] No more mirrors to try.
The key is Temporary failure in name resolution.
I think the domain resolution has problem. So Google it and find the answer.
Check file /etc/resolv.conf and make sure it only has the following entries.
I edit this file and add Google public DNS server into it.
So the file looks like following.
