Hi @mavenir-labs could you offer a minimal yaml manifest so I can reproduce this? Googling this error pointed me to a helm issue. Are you doing a helm based deployment?

Hi,
the problem occurs when I delete a Failed helm deployment of longhorn (https://longhorn.io/docs/0.8.0/install/install-with-helm/) .

root@microk8s:~# helm ls
NAME REVISION UPDATED STATUS CHART APP VERSION NAMESPACE
longhorn 1 Mon May 18 15:18:19 2020 FAILED longhorn-0.8.1 v0.8.1 longhorn-system

root@microk8s:~# helm delete --purge longhorn
Error: no kind "Job" is registered for version "batch/v1" in scheme "k8s.io/kubernetes/pkg/api/legacyscheme/scheme.go:30"

I can see that the job is there despite the error

root@microk8s:~# kubectl get jobs -A
NAMESPACE NAME COMPLETIONS DURATION AGE
longhorn-system longhorn-uninstall 1/1 4s 7s

This behavior does not occur on a 'generic' 1.18 kubernetes .

Thanks

Are you using the helm binary packaged with MicroK8s (microk8s enable helm)?

We may want to upgrade helm as indicated in helm/helm#6894 (comment)

yes , + tiller
kubectl create serviceaccount --namespace kube-system tiller
kubectl create clusterrolebinding tiller-cluster-rule --clusterrole=cluster-admin --serviceaccount=kube-system:tiller
helm init --client-only
helm init --service-account tiller --override spec.selector.matchLabels.'name'='tiller',spec.selector.matchLabels.'app'='helm' --output yaml | sed 's@apiVersion: extensions/v1beta1@apiVersion: apps/v1@' | microk8s.kubectl apply -f -

@mavenir-labs I just updated helm to 2.16.7. The snap will be on edge within the day and should be on the latest/stable channel with the 1.18.3 release.

To install the edge channel sudo snap install microk8s --classic --channel=latest/edge.

Please reopen the issue if the problem persists.

Hi,
I have updated microk8s with the following command,
snap refresh microk8s --classic --channel=latest/edge
got response --> microk8s (edge) v1.18.3 from Canonical✓ refreshed

but still helm is not updated,
Client: &version.Version{SemVer:"v2.16.0", GitCommit:"e13bc94621d4ef666270cfbe734aaabf342a49bb", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.16.0", GitCommit:"e13bc94621d4ef666270cfbe734aaabf342a49bb", GitTreeState:"clean"}

Do I need a clean install of microk8s to get helm updated ?

think I got it,
Just needed to re-init helm .

Thanks
