Wasted hours today trying to get kubeadm working on a Ubuntu VM. The culprit is a missing = for the pod-network-cidr parameter to the kubeadm init command when using calico. Without it kube-dns refused to start, oddly enough pods had 10.244.0.0 network setup but somehow it was failing sending a request to destroy and recreate the pod.
Here's the events for the kube-dns pods if someone's interested.
