Problem deploy Argo in Kubernetes

[pturanyi]

Hello
I am trying to deploy Argo in Kubernetes using Helm from https://github.com/argoproj/argo-helm

helm repo add argo https://argoproj.github.io/argo-helm
helm install my_argo argo/argo -n argo

But I get error:
manifest_sorter.go:192: info: skipping unknown hook: "crd-install"
Error: rendered manifests contain a resource that already exists. Unable to continue with install: ServiceAccount "argo-server" in namespace "argo" exists and cannot be imported into the current release: invalid ownership metadata; label validation error: missing key "app.kubernetes.io/managed-by": must be set to "Helm"; annotation validation error: missing key "meta.helm.sh/release-name": must be set to "my_argo"; annotation validation error: missing key "meta.helm.sh/release-namespace": must be set to "argo"

When I install into default namespace

helm install my_argo argo/argo

I get error:
manifest_sorter.go:192: info: skipping unknown hook: "crd-install"
Error: create: failed to create: Secret "sh.helm.release.v1.my_argo.v1" is invalid: metadata.name: Invalid value: "sh.helm.release.v1.my_argo.v1": a DNS-1123 subdomain must consist of lower case alphanumeric characters, '-' or '.', and must start and end with an alphanumeric character (e.g. 'example.com', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*')

What can I do?
