14.04: cups-pdf=2.6.1-9 fails to install inside a chroot

[cleary]

Description:
When installing cups-pdf inside a chroot as part of an unattended live build, it prompts for a password for the localhost root user.
This should not happen as per debian policy 3.9.1 (detailed below):

To quote the report in 539156:

"cups-pdf requires user interaction because of calling lpadmin in the
postinst script. This violates Debian policy "3.9.1 Prompting in
maintainer scripts". Quote: "Prompting must be done by communicating
through a program, such as debconf, which conforms to the Debian
Configuration Management Specification, version 2 or higher.""
