Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
kubeadm : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed
kubelet : Depends: kubernetes-cni (= 0.6.0) but 0.6.0-02 is to be installed
E: Unable to correct problems, you have held broken packages.

Make sure you've followed these steps accurarely, you seem to have missed on of these commands:

1. apt-get update && apt-get install -y apt-transport-https curl
2. curl -s https://packages.cloud.google.com/apt/doc/apt-key.gpg | apt-key add -
3. cat <<EOF >/etc/apt/sources.list.d/kubernetes.list
   deb http://apt.kubernetes.io/ kubernetes-xenial main
   EOF
4. apt-get update
5. apt-get install -y kubelet kubeadm kubectl
6. apt-mark hold kubelet kubeadm kubectl
