Lately I've been getting errors when I destroy a LXD environment:
$ juju destroy-environment lxd -y
ERROR while removing instance "juju-0e6aa300-1e3f-46ba-8adb-e42e3fa0f35a-machine-0":

Sometimes retrying the destroy-environment command will work, sometimes I have to 'lxc delete' instances.
This is with Juju 1.26-alpha3-trusty-amd64 (master 45caf1ce8ad1c59e3b72b4094b0cafb98c335ed9).
