How to resolve https://kubernetes-charts.storage.googleapis.com" is not a valid chart repository

Helm versions prior to 2.17.0 have the deprecated https://kubernetes-charts.storage.googleapis.com/index.yaml as the default stable repository, which no longer resolves. The new repo is https://charts.helm.sh/stable. You can choose to:

1. Use the --stable-repo-url argument to specify the new repository:

   helm init --stable-repo-url https://charts.helm.sh/stable --service-account tiller
   

2. Use the --skip-refresh argument and replace the stable repo:

   helm init --client-only --skip-refresh
   helm repo rm stable
   helm repo add stable https://charts.helm.sh/stable
   

3. Upgrade helm to 2.17.0 or later.

helm init --client-only --skip-refresh
helm repo rm stable
helm repo add stable https://charts.helm.sh/stable

update the urls like below solved my issue

Name : stable Old Location:https://kubernetes-charts.storage.googleapis.com
New Location:https://charts.helm.sh/stable

Name : incubator Old Location:https://kubernetes-charts-incubator.storage.googleapis.com New Location:https://charts.helm.sh/incubator

Reference:https://helm.sh/blog/new-location-stable-incubator-charts/

repo is not avail. use below repo.

k8scka@master:~$ helm3 repo add stable https://charts.helm.sh/stable
"stable" has been added to your repositories
k8scka@master:~$

I had this issue when targeting a helm_release resource in Terraform that was using the helm2 provider. We tracked it down to the root cause being a missing ~/.helm/repository/repositories.yaml file that helm2 uses, which must be also used by the Terraform provider.

The file can be recreated with a helm v2 client with

helm2 init --stable-repo-url https://charts.helm.sh/stable --client-only

There is no need to keep the helm v2 client afterwards if you only want to use Terraform.

Just for history and maybe anyone else will face also. Community answer.

Errors like "Error: error initializing: Looks like "https://kubernetes-charts.storage.googleapis.com" is not a valid chart repository or cannot be reached: Get https://kubernetes-charts.storage.googleapis.com/index.yaml: dial tcp 172.217.2.240:443: connect: connection timed out" are typically due to problems with Proxy and non-direct connection.

This was discussed in related github issue Cannot perform helm init behind proxy, lots have same problems. As per topic - users can have such problems with some of helm versions. Its recommended to use it starting from v2.11.0
