[lug] minikube (k8) question on Ubuntu 18.04

[Bear Giles]

I've installed minikube (single-node Kubernetes cluster designed for dev
and testing) and getting this error:

Starting local Kubernetes cluster...
E0827 07:51:38.946059    1363 start.go:83] Error starting host: Error
creating new host: dial tcp: missing address. Retrying.

It's reported fairly frequently and I've applied all of the previously
identified fixes but so far no luck.

Does anyone have an idea? I know that there was a 'dial' used back in the
era of dial-up modems but I doubt that's what this refers to. The system
has both docker and libvirt (kvm) installed.

I've investigated doing a full installation of K8 but that's... nontrivial.
I came across a reference to a docker image (that itself uses
docker-within-docker) so it's an option but most of the introductory
material assumes minikube.
