Helm has no deployed releases

Error

Helm upgrade failed for release my-cluster/my-cluster-namespace 
with chart Helm-create-namespace@0.1.0+9359778f813b: 
"my-cluster-namespace" has no deployed releases

Cause

The git repository named my-repo contains the workload cluster named my-cluster.

The helm release named my-cluster-namespace in namespace my-repo is trying to be installed but there is an issue.

The issue is that a secret indicate that the helm chart has been installed at least once but the helm chart is not able to retrieve the previous installation.

The secret name is : sh.helm.release.v1.my-cluster-namespace.v1

Solution

The solution is to delete the secret.

kubectl delete secret -n my-repo sh.helm.release.v1.my-cluster-namespace.v1
