Comment 1 for bug 1566757

I can confirm this bug. Happens to me if I try to preseed install Ubuntu Xenial (with Foreman). The bad news is, that the install fails because apt is unable update (with the error in sources.list) and so no packages for kernel etc. can be found. For me that means I cannot use Xenial at the moment (if I cannot use preseed install it makes no sense on an LTS release).
