Comment 7 for bug 1650651

Upgraded juju to version:

```
fengxia@local-charmdev:~$ juju --version
2.2.2-xenial-amd64
```

Issuing `juju deploy` command, under the `Message`, it says `copying image for ubuntu-trusty from https://cloud-images.ubuntu.com/release/: rootfs: 79%`.

Below is my local LXD image:

```
fengxia@local-charmdev:~$ lxc image info juju/trusty/amd64
