How can I list, show all the charts installed by helm on a K8s? If I run helm in a newly installed Ubuntu I cannot see which repos were used before to install the charts.
Kind of
helm show all *
Can I somehow export the helm's repository list and history from previously used server to the new ubuntu server? Where does helm keep the which repository installed etc?
Old ubuntu server
Helm repo list
NAME URL
gitlab https://charts.gitlab.io/
harbor https://helm.goharbor.io
bitnami https://charts.bitnami.com/bitnami
The New ubuntu server
Helm repo list
NAME URL
Thanks in advance

helm list --all-namespaces

By default in Secret objects in the same namespace as the release, but this can be changed.

Not really. You can use helm get values to get the set of values a particular release was installed with. I don't believe there's an option to tell you where the chart originally came from.
Rather than trying to export this information from a cluster, a better approach is to make sure you have a copy of the information you need to recreate it in source control. If the cluster state is small enough, you can try recreating it on a desktop-based Kubernetes installation (Docker Desktop, minikube, kind) for test purposes. This could be a directory of shell scripts with install commands and matching value YAML files; there are also higher-level tools like Helmsman and Helmfile that try to maintain an installation of several charts together.
