I'm installing a GUI on my centos 5 dedicated server. I got to the point where I needed to download x-window desktop and for some reason, it would not find a mirror that worked. Prior to trying to install x-windows, I installed KDE just fine through YUM.
Because yum could not find a suitable mirror for X, I did the command "yum clean all". After that, I tried yum update to update. This time however, I get this error:
Loaded plugins: fastestmirror
Determining fastest mirrors
Could not retrieve mirrorlist http://mirrorlist.centos.org/?releas...h=i386&repo=os error was
[Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
Error: Cannot find a valid baseurl for repo: base
This error now occurs whenever I use YUM and has started happening after i ran the yum clean all command.
