I'm upgrading an Ubuntu 14.04 LTS system to 14.10 over ssh with 'sudo do-release-upgrade'.
When it asks me if I want to continue doing this over SSH, the text ends with a blank line. If I press Enter at this point, only then I get to see the prompt, which was
Continue? [yN]
but by then it's too late and I already chose "no".
The same thing happens if I restart, go past this prompt (without seeing it), then ask for details about package removals/upgrades/installs. I get a list of packages in a pager. When I quit (by pressing q) I should once more see the prompt asking me if it's okay and if I should proceed, or cancel, or see the details again. But the prompt isn't there and doesn't appear until after I input my answer.
I think there's a missing sys.stdout.flush() call somewhere in do-release-upgrade.

[Impact]
Users upgrading from 14.04 and 14.10 via the command line "do-release-upgrade" will not be able to do so unless they figure out that they need to press "y" and Enter (without the benefit of a prompt).
[Test Case]
On an affected system, run 'sudo do-release-upgrade'
When it asks if you want to continue doing this over SSH, the text ends with a blank line. If you press Enter at this point, only then will you get to see the prompt, which was
Continue? [yN]
but by then it's too late and you already chose "no" by pressing Enter.
[Regression Potential]
The patch itself is quite small, just flushing output whenever we prompt the user. Should be safe.
