Cannot ship init spinnaker helm chart

[marccampbell]

I cannot ship init the spinnaker Helm chart.

$ ship version
{
    "version": "0.46.1",
    "buildTime": "2019-06-13T18:53:28Z",
    "dependencies": {
        "helm": "v2.14.1",
        "kustomize": "v2.0.3",
        "terraform": "v0.11.14"
    }
}

Then:

$ ship init github.com/helm/charts/stable/spinnaker
Reading github.com/helm/charts/stable/spinnaker ...

But you can't continue past the Helm Values screen.
