The “Unable to read consumer identity” error message in yum command when using Red Hat Network (RHN) usually indicates that yum is unable to locate the necessary information to identify the system and its entitlements. This can happen if the RHN subscription has not been properly set up or if there is a problem with the system’s profile on the RHN server.
To resolve the issue, you can try the following steps:
- Verify that your system is registered with RHN using the following command:
subscription-manager identity
- Make sure that the system is fully subscribed to all required channels by running:
subscription-manager list --available
subscription-manager attach --auto
- Disable any third-party repositories that might be conflicting with the RHN repositories:
yum-config-manager --disable <repo-id>
- Clean the yum cache to ensure that the latest information is being used:
yum clean all
- Try running the yum command again to see if the error has been resolved.
If the problem persists, you may want to contact Red Hat Support for further assistance.
