Hello, I updated my CentOS 6 machine yesterday and it threw this error at me (before I switched to centos-release-scl): http://mirror.centos.org/centos/6/SCL/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found" Trying other mirror. To address this issue please refer to the below knowledge base article https://access.redhat.com/articles/1320623 If above article doesn't help to resolve this issue please open a ticket with Red Hat Support. Did you miss this when removing Red Hat branding or is it supposed to say this? - Jitse
