The current cluster is based on RHEL 8.6 with GLIBC 2.28, while the OC binary is 4.19, which requires a newer glibc to compile, so the following issue will occur when running cnv automation:

oc: /lib64/libc.so.6: version `GLIBC_2.33' not found (required by oc) oc: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by oc) oc: /lib64/libc.so.6: version `GLIBC_2.32' not found (required by oc)

It will make the automation fail at:

It's better to set up the environment on RHEL 9 or CentOS 9.
