An glibc library error is shown when running the agent service in the SNO that it is about to be provisioned.

OCP - 4.13.0
MCE - 2.2.3

Always

1. Create the provisioning files required by MCE. They can be found here:https://github.com/alosadagrande/5g-ran-deployments-on-ocp-lab/tree/lab-4.13/lab-materials/sno-deployment  
2. Apply them. In my case I am using ZTP / OpenShift GitOps
3. An error is shown when the node is being registered
