To install Ubuntu on Kubernetes, follow these steps: 1. Set up a Kubernetes cluster using a managed service or tools like kubeadm. 2. Prepare Ubuntu nodes with the required version and network accessibility. 3. Install Docker on each Ubuntu node for containerization. 4. Install Kubernetes components (kubelet, kubeadm, kubectl) using apt-get. 5. Initialize the cluster with ""kubeadm init"" on one Ubuntu node. 6. Join other Ubuntu nodes to the cluster as worker nodes using provided instructions. 7. Set up a networking solution like Flannel, Calico, or Weave. 8. Verify the cluster's status with ""kubectl get nodes"" on the master node. Now, you have Ubuntu installed on Kubernetes. Utilize Kubernetes commands and manifests to deploy and manage containerized applications.

First u need to install mini kube then install this process. i got the solution
kube-flannel is CrashLoopBackOff and how to make it to running status
"Try using these two commands after initializing the master node: $ sudo kubectl apply -f raw.githubusercontent.com/coreos/flannel/ master/Documentation/kube-flannel.yml
$ sudo kubectl apply -f raw.githubusercontent.com/coreos/flannel/ master/Documentation/k8s-manifests/kube-flannel-rbac.yml
"
Please reinstall the VM, and clone it. After that follow the installation and put the commands in the same order.

Nice explanation..
But its too fast to see and understand (for me), while saving the file in sources.list
Where can I get etc,apt n sources.list on my computer..can you please help me with it
Thank you
This is just a copy paste command video... No explanation. No pre requisites.
Which leads to numerous errors.
Disspointed
Thank you for bringing this to our attention. We’re sorry you had a bad experience. We’ll strive to do better
