In my "Ubuntu 16.04", I use next steps to completely remove and clean Kubernetes (installed with "apt-get"):
kubeadm resetsudo apt-get purge kubeadm kubectl kubelet kubernetes-cni kube* sudo apt-get autoremove sudo rm -rf ~/.kubeAnd restart the computer.
use kubeadm reset command. this will un-configure the kubernetes cluster.
