No, you'll not break the dependency. If the package to update depends on a new package, then the package will be kept back when you use "apt-get update". "apt-get update" will not install new packages or remove un-needed packages automatically. "apt-get dist-upgrade" solves this issue. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
