Cannot Update CloudLinux 6 with Error "Error: Cannot find a valid baseurl for repo: base"

When trying to interact with yum, use EasyApache, or run updates, you are met with the following error:

Error: Cannot find a valid baseurl for repo: base

Description

The base, epel, extras, and updates repositories come default on CentOS 6 systems but are not used on CloudLinux systems. If they are accidentally re-activated, they can cause issues.

Workaround

You should disable these repositories to ensure your system continues to function properly:

yum-config-manager --disable base
yum-config-manager --disable epel
yum-config-manager --disable extras
yum-config-manager --disable updates

The CloudLinux variants of these repositories are still active and supersede these repositories.
