The reason that you couldn't find details is that the conf file process is handled by dpkg, rather than apt or update manager. Hopefully the details in the link clear things up. If you're impatient what you want is: apt-get -o Dpkg::Options::="--force-confdef" -o Dpkg::Options ::="--force-confold" dist-upgrade -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1077263 Title: default action to keep configuration files during dist-upgrade To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/update-manager/+bug/1077263/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
