Lab 6.4 can't execute crioctl run command always fails

armafehpe

Everytime that I run sudo crictl run container-config.json pod-config.json I got
E1123 16:53:51.688239 1912 remote_runtime.go:193] "RunPodSandbox from runtime service failed" err="rpc error: code = DeadlineExceeded desc = context deadline exceeded"
FATA[0004] running container: run pod sandbox: rpc error: code = DeadlineExceeded desc = context deadline exceeded

In systemctl status crio I got:
"CNI plugin not ready. Waiting to create k8s_busybox-sandbox_default_...

I checked the previous labd to check if I missed some step but looks I followed all steps.

After do some checking following google help, I noted that the directory /opt/cni/bin was empty and I got this solution:
# Example for downloading CNI plugins (adjust version as needed)
CNI_VERSION="v1.4.0" # Or the desired version
mkdir -p /opt/cni/bin
curl -L "https://github.com/containernetworking/plugins/releases/download/${CNI_VERSION}/cni-plugins-linux-amd64-${CNI_VERSION}.tgz" | tar -C /opt/cni/bin -xz

after do this, I can see the /opt/cni/bin with:
root@training1:~# ll /opt/cni/bin/

and then:
student@training1:~$ sudo crictl run container-config.json pod-config.json

student@training1:~$

Did I miss some step? or this step is missed from the lab?
