[lxc-users] can no longer install desktop environment into lxd container

I've done this for years now & then used either xrdp or x2go to access the
environment in the LXD containers.

But something has obviously changed as for 2 days now I've tried multiple
times to get either ubuntu-desktop or ubuntu-mate desktop to install and
the install always fails the same.  I cannot be sure but it looks like its
all due to bluez faling but maybe I don't know how to determine root cause.

*Errors were encountered while processing:*
* bluez*
* blueman*
* gnome-bluetooth*
* indicator-bluetooth*
* unity-control-center*
* gnome-user-share*
* pulseaudio-module-bluetooth*
* ubuntu-mate-core*
* ubuntu-mate-desktop*
* unity-control-center-signon*
*E: Sub-process /usr/bin/dpkg returned an error code (1)*

I am using LXD v 2.0.9

My host is:

*Distributor ID:    UbuntuDescription:    Ubuntu 16.04.2 LTSRelease:
16.04Codename:    xenial*

The container I am creating is AMD64 Xenial.

The container creates ok, I then "lxc exec cn1 bash" to access it.
apt update
apt upgrade
apt dist-upgrade

then install minimal ubuntu desktop (unity)

# apt install --no-install-recommends ubuntu-desktop

*I then see the above failures..*.

I stop the container and delete it.

I then recreate the container and try again but try to install Mate DE:

add-apt-repository ppa:ubuntu-mate-dev/xenial-mate -y

apt update

apt upgrade

apt install lightdm ubuntu-mate-core ubuntu-mate-desktop

*I then see the above failures again...*

Is this a change in LXD apparmor or capabilities preventing this install
from completion or should I be looking at launchpad bugs for bluez failures?

Thanks for any advice/guidance.

As I said I've been using the same scripts to install this for a long time
and its always worked successfully on Ubuntu 14.04 & on Ubuntu 16.04 until
