[Bug 1850672] Re: "precise esm -> trusty -> trusty new client" upgrade disables ESM

[Andreas Hasenack]

b) almost the same setup, but upgrading from precise to trusty with the
u-a-t proposed package, without going through the intermediary current
u-a-t from trusty-updates.

$ lxc launch ubuntu-daily:precise p1

$ lxc exec p1 -- bash -c "echo deb http://archive.ubuntu.com/ubuntu precise-proposed main > /etc/apt/sources.list.d/precise-proposed.list"
