Error: failed to download "kubernetes-dashboard" (hint: running `helm repo update` may help)

I am installing Kubernetes dashboard using helm 3 following the docs but getting below error:

  [root@localhost ~]# helm repo add kubernetes-dashboard https://kubernetes.github.io/dashboard/
    [root@localhost ~]# helm repo update
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "kubernetes-dashboard" chart repository
...Successfully got an update from the "stable" chart repository
Update Complete. ⎈ Happy Helming!⎈ 
    [root@localhost ~]# helm install kubernetes-dashboard/kubernetes-dashboard kubernetes-dashboard
Error: failed to download "kubernetes-dashboard" (hint: running `helm repo update` may help)

what should I do to fix this?

That chart is old and installs 1.x version of kubernetes dashboard.

From docs here use below command to install latest Kubernetes dashboard version 2.x

helm repo add k8s-dashboard https://kubernetes.github.io/dashboard
helm repo update
helm install dashboard-release k8s-dashboard/kubernetes-dashboard --version 2.2.0

The chart mentioned by Arghya is a must to use this period.

Alongside his answer, I want to mention very important info about the custom values of the Helm release :

#these are mine
rbac:
  clusterReadOnlyRole: true # <--- YOU NEED this one
  clusterAdminRole: false
extraArgs:
  - --enable-skip-login
  - --enable-insecure-login
  - --system-banner="Welcome to Company.com Kubernetes Cluster"

As you can see rbac.enabled is not enough, you need to specify also rbac.clusterReadOnlyRole=true or to give more access to the Dashboard, set true to rbac.clusterAdminRole.
