I believe this is a dupe of #4100 - which is fixed at head. I suspect this is because there is an invalid KUBECONFIG environment variable set.

Do you mind sharing:

• The exact command line you used to start minikube
• The output of env | grep KUBE (if you are using minikube with sudo, then use sudo env | grep KUBE

Please let me know if this helps.
