See the dpkg manual (man dpkg), specifically:
confnew: If a conffile has been modified always install
the new version without prompting, unless the
--force-confdef is also specified, in which case the
default action is preferred.
confold: If a conffile has been modified always keep the
old version without prompting, unless the --force-confdef
is also specified, in which case the default action is
confdef: If a conffile has been modified always choose
the default action. If there is no default action it will
stop to ask the user unless --force-confnew or
--force-confold is also been given, in which case it will
use that to decide the final action.
It's possible to pass these options to apt, for instance
apt-get -o Dpkg::Options::="--force-confold" upgrade
Hope that solves your problem.
