Comment 2 for bug 1624028

I understand the debian image is not working properly (or doesn't exist).
Using sudo lxc-create -n debian01 -t download we get the list of valid distro/release/arch available, and specifying:
     Distribution: debian
     Release: sid
     Architecture: ppc64el
works on debian and on ubuntu !.

Downloading the image index
Downloading the rootfs
Downloading the metadata
The image cache is now ready
Unpacking the rootfs

---
You just created a Debian container (release=sid, arch=ppc64el, variant=default)

To enable sshd, run: apt-get install openssh-server

For security reason, container images ship without user accounts
and without a root password.

Use lxc-attach or chroot directly into the rootfs to set a root password
or create user accounts.
