This is a test repository designed to test the idea of having a deprecated chart version that doesn't break an installed application but tells you the repository is deprecated and you can't install the upgrade.
Here's how you can test it....
helm repo add deprecated https://mattfarina.github.io/dep-repo-test/
helm install foo deprecated/wordpress --version 9.0.3
# Wait for it to come up if you want
helm upgrade foo deprecated/wordpress
You should get an error but the existing service running in Kubernetes is untouched.

helm install --name foo deprecated/wordpress --version 9.0.3
# Wait for it to come up if you want
helm upgrade foo deprecated/wordpress
