failed to install kubeadm

[Kube-ASY]

What happened:
I tried to install a new KubeOne cluster with the following config:

apiVersion: kubeone.io/v1alpha1
kind: KubeOneCluster
name: demo
versions:
  kubernetes: "1.13.2"
cloudProvider:
  name: "none"
hosts:
- publicAddress: '1.2.3.4'
  privateAddress: '172.18.0.1'
  sshPort: 22 # can be left out if using the default (22)
  sshUsername: ubuntu
machineController:
  deploy: false
  provider: "none"

This failed with the following issue:
