IIRC networking on unprivileged systemd container was broken due to
some changes in systemd. This is true even on current release (vivid).
If this hasn't been fixed, then you can't use unprivileged wily as-is,
regardless whether dbus is installed or not. There are workarounds for
this (including creating custom systemd units).

You should always be able to configure network manually though (e.g.
"ifconfig"). Another workaround is to use "lxc-attach -s", and ommit
network namespace, so that the container would use host's networking,
thus you will be able to install packages using apt-get.
