Hi @Sajid Farooq - I also get that error if you are trying to spawn a cluster with latest kubeadm version (v1.24.2). Try it with lower version i.e. with v1.23.2, it should work.

@unnivkn I am not able to install cri-o in OS (ubuntu 18.04). I am trying to build like (Section 11: Installing Kubernetes the kubeadm way). Please suggest to me how should I move forward. I am stuck for the past few days. One master and two worker nodes. I am still failing at CRI installations.
