Helm chart failed to download

When trying to do a list on helm by below command I am able to see the list of charts currently deployed in GKE cluster

helm list --all-namespaces

NAME    NAMESPACE REVISION    UPDATED       STATUS          CHART           APP VERSION
abc-cd  in-gke    1           2023-01-06    deployed        cd-5.16.14      v2.5.5

However when trying to download , it's throwing download error

$ helm show chart cd-5.16.14
Error: failed to download "cd-5.16.14"

Also helm repo showing blank , not sure if this has any significance as I can already see the charts

$ helm repo list
Error: no repositories to show

helm list --all-namespaces shows the releases that are already installed in your k8s cluster, and helm show shows information about the chart.

"A Chart is a Helm package. It contains all of the resource definitions necessary to run an application, tool, or service inside of a Kubernetes cluster.

A Repository is the place where charts can be collected and shared.

A Release is an instance of a chart running in a Kubernetes cluster. One chart can often be installed many times into the same cluster. And each time it is installed, a new release is created." - from Helm documentation

Now if you are getting no response from helm repo list means that you need to add local repositories, and then you may need to update them. To do that use:

If it didn't work for some reasons, you may try helm repo add with --force-update as recommended in different troubleshooting scenarios here: https://helm.sh/docs/faq/troubleshooting/

If it worked you would be able to run helm show REPO_NAME/CHART_NAME.

In case you lost access to the chart or its repository, or it was deployed from a local helm chart that was not published to an artifactory. You can get the rendered manifest with helm get manifest RELEASE, with your example's inputs it will be:

helm get manifest abc-cd --namespace in-gke

And this won't show your helm values to get that you can try with helm get values RELEASE_NAME [flags], which would be something like:

helm get values abc-cd --namespace in-gke --all

Also, if any of these commands fail add --debug or set HELM_DEBUG=1.

I hope this was helpful :)
