That changed today to now use the helm chart under the covers. We now recommend people who do not have OperatorHub to install Kiali Operator using the Kiali Helm Chart. If you use the deploy script now, it will be using the helm chart underneath.
So this should do what you want: bash <(curl -L https://raw.githubusercontent.com/kiali/kiali-operator/v1.16.0/deploy/deploy-kiali-operator.sh) --uninstall-mode true
Now one thing I do see however is that it doesn’t delete the kiali-operator namespace because it says there is a pod still running. Checked and the kiali-operator pod is still running there. Shouldn’t the script still delete it?
