I upgrade to 2.5.2, and when I tried to upgrade applications install previously from 2.4 (from app and marketplace).
They failed with
helm upgrade --history-max=5 --install=true --namespace=metallb --timeout=10m0s --values=/home/shell/helm/values-metallb-1.0.1.yaml --version=1.0.1 --wait=true metallb /home/shell/helm/metallb-1.0.1.tgz Release "metallb" does not exist. Installing it now. Error: rendered manifests contain a resource that already exists. Unable to continue with install: PodSecurityPolicy "metallb-speaker" in namespace "" 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 "metallb"; annotation validation error: missing key "meta.helm.sh/release-namespace": must be set to "metallb"
Not sure it has anything to do with helm2 deprecation and more to another helm repo…
