Moving from pyjuju to juju-core

[Matthew Williams]

I've just started playing around with juju core and I'm having trouble 
getting going.

Here are some of my notes so far, hope folks are able to give me some 
pointers

I can't seem to setup a local environment. I get the following error:
 > error: environment "local" has an unknown provider type "local"

I can't specify an ec2-uri (to be able to use canonistack)

 > error: ec2-uri: expected nothing, got "<uri>"

When I tried to deploy my charm - which works on pyjuju I get "hook 
failed: install" however in the unit there is no /var/lib/juju/units 
directory which is where I would normally go to see the charm.log file. 
Where should I be going to see logs?

Thanks

Matt
