Red Hat 7 - Amazon EC2 - Could not retrieve mirrorlist https://None/pulp

Question

SELinux is running in permissive mode

yum update is yielding:

Loaded plugins: amazon-id, rhui-lb, search-disabled-repos Webmin
| 1.0 kB 00:00:00 Could not retrieve mirrorlist https://None/pulp/mirror/rhui-client-config/rhel/server/7/x86_64/os error was 14: curl#6 - "Could not resolve host: None; Name or service not known"

This is a fresh Amazon Red Hat 7 box, with webmin and a LAMP stack.

Solution 1

Had the same issue, the resolution was that, edit /etc/yum.repos.d/rhui-load-balancers.conf with

rhui2-cds01.eu-central-1.aws.ce.redhat.com
rhui2-cds02.eu-central-1.aws.ce.redhat.com

Solution 2

I restored the rhui-load-balancers.conf file and that resolve the issue.

yum.repos.d/rhui-load-balancers.conf

rhui2-cds01.us-east-1.aws.ce.redhat.com

rhui2-cds02.us-east-1.aws.ce.redhat.com

rhui could not determine what region your instance is running in. This doesn't look like an SELinux issue. Though, it could have been caused by installing Webmin. Start over with a new instance, and this time, don't install Webmin.

Make sure that that is the correct region. If it is not, then you may be charged for data transfer.
