Yolanda Robla d5a6a7cb44 Add force-confdef in debian package install
In certain cases, with packages cached that need an upgrade,
when performing that action the system hangs waiting for
a prompt.
Add force-confdef option, that will let dpkg overwrite
configuration packages that were not modified. In combination
with already existing force-confold flag, it will allow
to avoid any conffile prompt.
