<p>How can I diagnose this further?</p>

<p>Here are the currently running pods in <code>kube-system</code>:</p>

<pre><code>vagrant@ubuntu-xenial:~$ kubectl get pods -n kube-system

<p>The issue was with the deployment / service account not being present.</p>

<pre><code>vagrant@ubuntu-xenial:~$ kubectl get deployment tiller-deploy --namespace kube-system
NAME            READY   UP-TO-DATE   AVAILABLE   AGE
tiller-deploy   0/1     0            0           24h


vagrant@ubuntu-xenial:~$ kubectl get events --all-namespaces
kube-system     4m52s       Warning   FailedCreate    replicaset/tiller-deploy-7f4d76c4b6                 Error creating: pods "tiller-deploy-7f4d76c4b6-" is forbidden: error looking up service account kube-system/tiller: serviceaccount "tiller" not found
</code></pre>

<hr>

<p>I deleted the deployment and ran <code>helm init</code> once again which then worked:</p>

<pre><code>kubectl delete deployment tiller-deploy --namespace kube-system
helm init
</code></pre>
