Kubernetes' Kubeadm stops at apiclient -

i have created new ubuntu 16.04 droplet on digitalocean , followed guides respectively install kubeadm (and dependencies):

https://docs.docker.com/engine/installation/

https://kubernetes.io/docs/tasks/tools/install-kubectl/

https://kubernetes.io/docs/setup/independent/install-kubeadm/

however, when run kubeadm init, get:

i tried create new centos 7 droplet apply different instructions centos, , got same problem.
