To be honest, I don't see how this exact failure is LXC related?
The post script of ubuntu-keyring fails and thus the creation of the
container fails. Pretty normal IMHO. Or does it work fine outside LXC?

Can you reproduce the issue with `-r xenial`? It seems the Ubuntu
template tries to bootstrap outdated Precise by default [1].
