none: minikube dashboard --url outputs nothing (v0.28.2)

[ghost]

Environment:
minikube version: v0.28.2
OS:
NAME="Ubuntu"
VERSION="16.04.4 LTS (Xenial Xerus)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 16.04.4 LTS"
VERSION_ID="16.04"
HOME_URL="http://www.ubuntu.com/"
SUPPORT_URL="http://help.ubuntu.com/"
BUG_REPORT_URL="http://bugs.launchpad.net/ubuntu/"
VERSION_CODENAME=xenial
UBUNTU_CODENAME=xenial

What happened:
I used the command "minikube start --memory=8192 --cpus=4 --kubernetes-version=v1.10.0
--extra-config=controller-manager.cluster-signing-cert-file="/var/lib/localkube/certs/ca.crt"
--extra-config=controller-manager.cluster-signing-key-file="/var/lib/localkube/certs/ca.key"
--vm-driver=none" and "minikube start --vm-driver=none" to install minikube !
minikube was installed OK ! but didn't install related pods of the addons-manager and the dashboard ! then i followed some guild at the kubernets official website ! input command " kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml" to deploy dashboard for minikube ! and then the dashboard was deployed well !but i input command "minikube dashboard --url" to check dashboard url !but still output nothing !
The following screenshot was detailed pods install status of the kube-system namespace !
root@seliius07751:/etc/kubernetes# kubectl get pods -n kube-system

What you expected to happen:
Maybe two weeks ago ! I use above commands to install minikube ! and the dashboard always was deployed by default !
How to reproduce it (as minimally and precisely as possible):

1. stop and delete pre-installed minikube
   minikube stop;minikube delete
2. delete some file about minikube
   rm -rf /home/.mikube /home/.kube
   rm -rf /etc/kubernetes/
3. reinstall minikube
   minikube start --vm-driver=none or
   minikube start --memory=8192 --cpus=4 --kubernetes-version=v1.10.0
   --extra-config=controller-manager.cluster-signing-cert-file="/var/lib/localkube/certs/ca.crt"
   --extra-config=controller-manager.cluster-signing-key-file="/var/lib/localkube/certs/ca.key"
   --vm-driver=none" and "minikube start --vm-driver=none

What does kubectl version output on your machine?

I ask because I noticed that kubectl with a very old (July 2017) had an issue with showing the URL for the new dashboard setup.

I think maybe my kubectl version not very old ! The following content is my kubectl version detailed message !

I'm curious if this is still seen with minikube v0.30.0 - we changed the way the dashboard is accessed, by plumbing it through kubectl proxy.

i don't know why that time dashboard didn't automatic deployment ! but after i spent some times to clear minikube configuration and images ! then dashboard can be automatic installed ! so you can close this issue !
