Public bug reported:
Steps to reproduce:
1. On Wily, "lxd-images import ubuntu --alias xenial --stream daily xenial
amd64" (lxd is 0.20-0ubuntu4.1 on the host, but I don't think that matters for
this bug).
2. Start a container using "lxc launch xenial test"
3. Enter the container with "lxc exec test -- login -f ubuntu"
4. "sudo apt-get update && sudo apt-get dist-upgrade" (this will run inside the
container). This wants to bump "dbus gettext-base klibc-utils libasprintf0v5
libdbus-1-3 libedit2 libgcc1 libklibc libpam-systemd libparted2 libseccomp2
libsystemd0 libudev1 lxd lxd-client parted sed systemd systemd-sysv udev" and
install new package gcc-6-base.
Expected result: success
Actual result:
Setting up lxd (2.0.0~beta2-0ubuntu1) ...
Job for lxd.service failed because a timeout was exceeded. See "systemctl
status lxd.service" and "journalctl -xe" for details.
invoke-rc.d: initscript lxd, action "start" failed.
dpkg: error processing package lxd (--configure):

Errors were encountered while processing:
lxd
E: Sub-process /usr/bin/dpkg returned an error code (1)
Prior to the upgrade, lxd inside the Xenial container is on
2.0.0~beta1-0ubuntu4. The postinst takes a while to time out. During that time,
"ps axf" shows me:

I pulled the Xenial image today.

If this bug is valid, then can I suggest that this use case be added to CI? I
feel that it's a common use case for Ubuntu devs.
