Helm dependency update returns an error if two chart have dependencies having the same name but different repo #7411
Description
Edit: See #7413 before.
If:
- There is a chart defining two dependencies having the same name but from two different repositories
- one of those repositories is in the global repository list (or any other repository containing a chart with the same name)
Then helm dependency update will throw an Error: could not find : no matching version error.
Example:
Content of global repositories.yaml:
apiVersion: ""
generated: "0001-01-01T00:00:00Z"
repositories:
- caFile: ""
certFile: ""
keyFile: ""
name: stable
password: ""

BUT if content of repositories.yaml does not contain the stable repository (nor the elastic repository) but contains something unrelated or is empty:
apiVersion: ""
generated: "0001-01-01T00:00:00Z"
repositories:
- caFile: ""
certFile: ""
keyFile: ""
name: jetstack
password: ""
url: https://charts.jetstack.io
username: ""Then the same above commands will work.
