Hi I am trying to install kubernetes on a vm with ubuntu 14.04, using manual from http://kubernetes.io/docs/getting-started-guides/ubuntu/ I tried

KUBERNETES_PROVIDER=ubuntu ./kube-up.sh

I am getting following error:

etcd start/pre-start, process 1557
Error:  client: etcd cluster is unavailable or misconfigured
error #0: dial tcp 127.0.0.1:4001: getsockopt: connection refused
error #1: dial tcp 127.0.0.1:2379: getsockopt: connection refused

Following is the content of /var/log/upstart/etcd.log:

2016-10-24 13:28:54.270052 I | etcdmain: stopping listening for peers on http://localhost:2380
