    Thank you Sai for your inputs. i was getting journalctl -xeu kubelet output was Error while dialing dial unix /var/run/cri-dockerd.sock: connect: no such file or directory i was restarted and enabled cri-dockerd services

    • sudo systemctl enable cri-dockerd.service
    • sudo systemctl restart cri-dockerd.service

    then sudo systemctl start kubelet finally it works for me.

    #kubectl cluster-info Kubernetes control plane is running at https://127.0.0.1:6443

    this link will give https://github.com/kubernetes-sigs/kubespray/issues/8734 more info. Regards,Zain

    Below step can solve your issue.
    kubelet may be down, use the below commands on the master node.

       1. sudo -i

   2. swapoff -a

   3. exit

   4. strace -eopenat kubectl version

    Then try using kubectl get nodes.

    This work for me, I’m using minukube,

    When checking the minikube status by running the command minikube status you’ll probably get something like that

        E0121 07:14:19.882656    7165 status.go:415] kubeconfig endpoint: got: 
    127.0.0.1:55900, want: 127.0.0.1:49736

    type: Control Plane
    host: Running
    kubelet: Stopped
    apiserver: Stopped
    kubeconfig: Misconfigured

    To fix it, I just followed the next steps:

    1. minikube update-context
    2. minukube start
