I am using yum update command with RHN to upgrade packages installed on my server, but getting the following warning on screen :
yum update -y
Loaded plugins: product-id, protectbase, rhnplugin, security, subscription manager:
Updating certificate-based repositories.
Unable to read consumer identity
0 packages excluded due to repository protections
Setting up Update Process
--> Running transaction check
How do I get rid of this warning /error under RHEL 6 server?
You need to edit the following files
Use a text editor such as vi:
# vi /etc/yum/pluginconf.d/product-id.conf /etc/yum/pluginconf.d/subscription-manager.conf
Set enabled to 0 as follows in both files:
Save and close the file. Finally, type the following command to clean cache:
rm -rfv /var/cache/yum/*
yum clean all
You can now install or update the system:
# yum install packageNameHere
# yum -y update
As per RHEL KB # 165803 root cause for this error was:
When RHN Classic or RHN Satellite is used for updating the system, subscription-manager should be disabled.
