Your OS and Docker version are not supported anymore. I am surprised that anyone even runs such an old version.

I wouldn’t be surprised if you run an outdated k8s version on top of it, since docker support was removed in Kubernetes 1.24, which is the smallest supported version at the time being.

issue resolved. I upgraded UBUNTU to root@K8s-Master:~# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 18.04.6 LTS
Release: 18.04
Codename: bionic

I also faced another issue which resolved when I stop kubelet process

root@K8s-Master:~# kubeadm init --apiserver-advertise-address=192.168.2.178 --pod-network-cidr=192.168.0.0/16

ISSUE
[ERROR Port-10250]: Port 10250 is in use
RESOLUTION
netstat -anp |grep 10250
systemctl stop kubelet

Now when the kubeadm init job starts it finishes successfully and kubelet also started on another port
