[Bug 1563168] [NEW] 14.04 -> 16.04 upgrade in lxd container dies most of the way through

[Michael Hudson-Doyle]

Public bug reported:

This sounds a bit like bug #1555237 but I'm not sure it's the same.

Basically I did this: started a lxd container with "lxd launch ubuntu-
daily:trusty", sshed into it (I have cloud-init data configured to set
this up) and ran do-release-upgrade -d. I answered "no" to all questions
(restart services without asking, asked it not to restart anything due
to the openssl upgrade, not to replace whichever file you get asked
about) and then, finally, as it was asking me if I wanted to reboot or
not, my ssh session dropped (it had probably been idle at that prompt
for a while).

I see this when I log back in:

ubuntu at lts2lts:~$ sudo screen -ls
sudo: unable to resolve host lts2lts
There is a screen on:
	2413.ubuntu-release-upgrade-screen-window	(03/29/2016 02:37:27 AM)	(Dead ???)
Remove dead screens with 'screen -wipe'.
1 Socket in /var/run/screen/S-root.

And while I haven't checked exactly, it seems like the container has
"rebooted".

I've uploaded /var/log/dist-upgrade/ from the container to
http://people.canonical.com/~mwh/dist-upgrade-logs.tgz.

This seems to be reproducible, although exactly when the ssh connection
drops seems a bit variable.
