 This usually is an indication that Tiller was not installed with enough permissions to create the resources required by Kubeapps. In order to install Kubeapps, tiller will need to be able to install Custom Resource Definitions cluster-wide, as well as manage app repositories in your kubeapps namespace. The easiest way to enable this in a development environment is install Tiller with elevated permissions (e.g. as a cluster-admin). For example:
 
-```

 kubectl -n kube-system create sa tiller
 kubectl create clusterrolebinding tiller --clusterrole cluster-admin --serviceaccount=kube-system:tiller
