Good morning all, I ran an 'yum update' and have been receiving the following errors:
Loaded plugins: fastestmirror Determining fastest mirrors Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=x86_64&repo=addons error was [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')> Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=x86_64&repo=os error was [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')> Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=x86_64&repo=extras error was [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')> Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=5&arch=x86_64&repo=updates error was [Errno 4] IOError: <urlopen error (-3, 'Temporary failure in name resolution')>
