kiali: Latest installation script seems to be broken

Describe the bug I’m following the installation documentation, and I’m running the command curl -L http://git.io/getLatestKialiKubernetes | bash. However here is the output that I’m receiving:

kubectl is here: /usr/local/bin/kubectl
envsubst is here: /usr/local/opt/gettext/bin/envsubst
Will use the last Kiali release:
readlink: illegal option -- f
usage: readlink [-n] [file ...]
usage: dirname path
Deploying Kiali to kubernetes project istio-system
Downloading YAML via: wget -q -O - https://raw.githubusercontent.com/kiali/kiali//deploy/kubernetes/secret.yaml
error: no objects passed to create
ERROR: Failed to deploy to kubernetes. Aborting.

Looks like the default VERSION_LABEL is not set correctly to the latest version.

Versions used Kiali: Latest Istio: 1.0.3 Kubernetes flavour and version: Kubernetes 1.10

Maybe this is the something that I have to additionally configure on my system, but in this case maybe this could be described in the documentation. If this is confirmed as a bug or the documentation needs to be extended I can try to work on this issue.

There is a workaround for this: export IMAGE_VERSION=latest; curl -L http://git.io/getLatestKialiKubernetes | bash
