oc cluster-version approve-csr <csr-name>
Why it's wrong here
This subcommand does not exist under cluster-version.

oc adm certificate approve <csr-name>
Why this is correct
This command approves pending certificate signing requests, allowing nodes to join the cluster.
- ✗
oc patch csr <csr-name> --type=json -p='[{"op": "replace", "path": "/status/conditions", "value": "Approved"}]'
