Comment 3 for bug 1582896

The error is internal to lxd. This might not be a juju bug. Does LXD work fine when you directly used it? You can you run these commands:

# If you haven't already used lxd?
lxc image copy ubuntu:xenial local: --alias xenial

# Once xenial is registerest, these commmands should be repeatable.
lxc launch xenial me
lxc list
lxc exec me -- hostname
lxc stop me
lxc delete me
