juju status ERROR current model controller devlocal not found

[fengxia]

Hi Juju,

I had a localhost controller bootstrapped and deployed 8 machines (LXDs) 
to it. Host is a KVM vm of Ubuntu 16.04 amd64.

Now for some strange reason, `juju status` reports error as if it lost 
its model? `list-controllers` showed the controller looks fine. `lxc 
list` shows all the machines are up and running.

Any idea of what this error is about, and how to debug it?
