The instructions are fine, what needs fixing is the package in Ubuntu
15.04 so that it actually starts the daemon automatically as it should
(that's been fixed since, just not backported to 15.04).

As for lxd-images, are you running it from the same shell your ran newgrp from?

To clarify how newgrp works, it will spawn a new shell inside the shell
it's called from which will be in the group you passed it, all your
other shells still lack the group membership. The only way to fix group
membership for all shells is to logout and login again.
