Failure while attempting to deploy charm

[Sean Feole]

I have been having this problem when trying to use Amulet as of Friday night(1/24/2014). After importing and attempting to add a new charm, I receive the following error after running d.setup() , I have tried using amulet from trunk and the packaged source.

Below is a quick example of adding memcached, In my /tmp dir it appears that the
amulet_deployment_XXXXX directory is always created with the appropiate permissions however they are continuously empty. I know there was some updates to amulet late last week, but I think this may be more of a configuration/environment issue on my half.

In [2]: d = amulet.Deployment()

In [3]: d.add('memcached')

In [4]: d.setup()

OSError: Unable to update bzr repo

To Reproduce This:

Start from a freshly installed OS.

1.) Create an instance with canonistack
2.) Log into the instance and issue the following:

sudo add-apt-repository ppa:juju/stable
sudo apt-get update
sudo apt-get install amulet

3.) Install Ipython3

sudo apt-get install ipython3

4.) launch ipython3 and issue the following

import amulet
d = amulet.Deployer()
d.add('mysql')
d.add('mediawiki')
d.relate('mysql:db', 'mediawiki:db')
d.expose('mediawiki')
d.setup()

After Issuing d.setup() the bzr repo will fail to create.

I forgot to add that juju-core must be installed and configured prior to running through step#2

[Marco Ceppi (marcoceppi)]

This is due to bzr not knowing "whoami" patched in trunk

This has been fixed with the latest amulet package 1.2.1-0ubuntu1~ubuntu13.10.1~ppa1 ,, thanks!
