Comment 4 for bug 1543764

The community built images on images.linuxcontainers.org will still exist, nothing's going to change on that side, so anyone using images.linuxcontainers.org as a remote will still be getting those images.

Those images just aren't Canonical built, official Ubuntu images, so our products really shouldn't be using those.

LXD is getting native simplestreams support very soon, at which point, both the daemon (through REST API) and the client will know how to interact with simplestreams.

We will have an hardcoded "ubuntu" remote in the client which you'll be able to use to interact with cloud-images.ubuntu.com, likely something along the lines of: lxc launch ubuntu:xenial blah
