error container not ready

```
[root@node1 ~]# kubectl exec virt-operator-597d676ff5-qhkms -n kubevirt -- ls /etc/virt-operator/certificates
tls.crt
tls.key
[root@node1 ~]# kubectl debug virt-operator-597d676ff5-qhkms -n kubevirt
error: container [virt-operator] not ready
```

The report only provides a kubectl debug command and the "container [virt-operator] not ready" error; start by reproducing it against the stated pod and reviewing kubectl-debug's container-selection behavior. Done would require an agreed behavior for containers reported as not ready, plus a confirmed fix or documented limitation, but the repository is marked unmaintained.
