I have a minimal CentOS 6.4 running off a VM through VirtualBox in Bridged mode. Fedora 19 is the host. I am completely unable to use yum update. Whenever I try, I get this error:
Error: Cannot find a valid baseurl for repo: extras
I tried googling extensively for an answer, but none of the suggestions (like try yum clean all, use google DNS, or uncomment #base= line in /etc/yum.repos.d/ files) are making any difference.
Please help me resolve this headache.
