Comment 8 for bug 130519

I solved this by installing 'dialog' as recommended here: http://forum.doozan.com/read.php?2,502,502,quote=1

I still don't really understand the error message, so I'm not sure if I should not be doing what I'm doing, but at least it's silent now. ;)

In my case, I'm running apt-get remotely from a deployment script (Fabric), so I definitely can't interact with it. I'm (totally not) looking forward to finding out what happens the first time apt-get expects input from me during the process... :(
