yum gives error : 'Temporary failure in name resolution

[Empires]

Hi i m new to Linux.
I tried using 'yum' command to update

"yum update"

but it gave following error:.

Could not retrieve mirrorlist http://mirrors.fedoraproject.org/mir...ra-7&arch=i386 error was
[Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Error: Cannot open/read repomd.xml file for repository: fedora

what should i do?

Thanks in advance.

Try yum clean all and then try yum again. If it still fails, wait 5-10 minutes and try again. Fedora yum is fast when the repos aren't slammed for requests, but when they're being hit hard, they really slow down.

Here's a link to the Fedora project wiki w/regards to yum through a proxy.

Temporary failure in name resolution

means that DNS server is unable to translate address mirrors.fedoraproject.org
you can simply verify that when you do "host mirrors.fedoraproject.org" it will return error.

Type this into your /etc/hosts file:

66.35.62.162 mirrors.fedoraproject.org

It should help yum with name translation.
However, you should examine your DNS confiuration, check settings in /etc/resolv.conf and in your local bind (if you have one), because this behavior is not normal.

Thanx a lot. Now yum is working fine.
