Go version: Don't know (using a PaaS solution so no access to VM's)

Steps to reproduce

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml --validate=false

Comments

have a new installed AKS cluster and I know the dashboard is already running on the cluster by default, but it is using a different/lower version of the dashboard:
k8s-gcrio.azureedge.net/kubernetes-dashboard-amd64:v1.6.3

And I would like to use this version.

@PriyankaGupta05 running helm upgrade --force helped me. Credit: https://github.com/helm/charts/pull/13545#issuecomment-491135192

This solution applies only to those who installed dashboard via helm. I'm still leaving it here just in case, because I googled the same error and ended up in this issue myself.

I have resolved this issue by kuberctl delete -f kubernetes-dashboard.yaml. Then apply it again.

Having the same problem on Kubernetes-version 1.14.8.

I have resolved this issue by kubectl delete -f kubernetes-dashboard.yaml. Then apply it again.

This was the solution for me as well (watch the minor typo, kubeRctl instead of kubectl (fixed in quote)
