The issue is that you have changed these files from the defaults. The
package maintainers may have made a change to the way the package works
that is incompatible with your changes, so its important to see those
differences and *decide* whether to keep your config file or merge their
changes into it (or just take theirs).

Please use extreme caution before proceeding..

Still, to force one or the other, you can force it to keep your version
(the default):

apt-get -o DPkg::Options=--force-confdef

or make it take the new packager's config file with:

apt-get -o DPkg::Options=--force-confnew
