Unable to read consumer identity
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
repo id repo name
rhui-rhel-8-for-x86_64-appstream-rhui-rpms Rocky Linux 8 for x86_64 - AppStream from RHUI (RPMs)
rhui-rhel-8-for-x86_64-baseos-rhui-rpms Rocky Linux 8 for x86_64 - BaseOS from RHUI (RPMs)
How to Fix
The subscription manager plugin must be disabled (change enabled=1 to enabled=0) to remove the warnings as the updates are fetched from RHUI via CDS (Content Delivery Server).
# cat /etc/yum/pluginconf.d/subscription-manager.conf
[main]
enabled=1
Origin of the Problem
- The Red Hat Update Infrastructure includes components like RHUA (Red Hat Update Appliance) and CDS.
- The RHUA downloads the new packages from Red Hat’s CDN (Content Delivery Network) which gets copied to CDS nodes.
- The RHEL clients intergrated with RHUI receives updates from repositories provided by CDS nodes.
- The RHUI systems need not be registered with subscription manager which generates the warning.
This system is not registered to Red Hat Subscription Management.
Diagnostic Steps
- Confirm the RHUI client rpm is installed in the system.
# rpm -qa | grep rhui-client*
- CDS URL’s will be used by the repo configuration.
# grep mirrorlist /etc/yum.repos.d/rh-cloud.repo
