Istio with Helm is failed

Hi,

I would like to install Istio with Helm.
I read Istio with Helm but got an error.

$ helm install istio-base manifests/charts/base -n istio-system
Error: failed to download "manifests/charts/base" (hint: running `helm repo update` may help)

I tried to add a chart repository but I couldn’t.

$ helm repo add istio.io https://storage.googleapis.com/istio-release/releases/1.9.2/charts/
Error: looks like "https://storage.googleapis.com/istio-release/releases/1.9.2/charts/" is not a valid chart repository or cannot be reached: failed to fetch https://storage.googleapis.com/istio-release/releases/1.9.2/charts/index.yaml : 404 Not Found

Any idea how can I do?
Thank you.

You’re not on the right path/folder. ex:.

wget https://github.com/istio/istio/releases/download/1.9.3/istio-1.9.3-linux-amd64.tar.gz
tar -zxf istio-1.9.3-linux-amd64.tar.gz
cd istio-1.9.3
helm install istio-base manifests/charts/base -n istio-system
