<p>Minikube not starting with several error messages. 
kubectl version gives following message with port related message:</p>

<pre><code>iqbal@ThinkPad:~$ kubectl version
Client Version: version.Info{Major:"1", Minor:"12", GitVersion:"v1.12.2", GitCommit:"17c77c7898218073f14c8d573582e8d2313dc740", GitTreeState:"clean", BuildDate:"2018-10-24T06:54:59Z", GoVersion:"go1.10.4", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost:8080 was refused - did you specify the right host or port?
</code></pre>

<p>You didn't give more details, but there are some concerns that I solved few days ago about minikube issues with kubernetes <strong>1.12</strong>.</p>

<p>Indeed, the compatibility matrix between kubernetes and docker  recommends to run : 
Docker <strong>18.06</strong> + kubernetes <strong>1.12</strong> (Docker 18.09 is not supported now).</p>

<p>Thus, make sure <code>docker version</code> is NOT above <strong>18.06</strong>. Then, run the following:</p>

<pre><code># clean up
minikube delete

minikube start --vm-driver="none"
kubectl get nodes
</code></pre>

<p>If you are still encountering issues, please give more details, namely <code>minikube logs</code>.</p>
