Install guide recommend

• kubeadm https://skyao.io/learning-kubernetes/docs/installation/kubeadm/ubuntu.html
• MicroK8s
  • Just follow the official guide,
  • but somehow it became extremely slow after re-installed, I did all what I can do to entirely remove, but still.
• For ubuntu, really helpful tutorial
