There is a lot of confusion in this thread. dist-upgrade is NOT (in most cases) meant to upgrade to a newer distribution (eg. Ubuntu 14.04 to 16.04). dist-upgrade is just like upgrade except it also installs additional packages if necessary (eg. linux-kernel-4.1 AND linux-kernel-4.2). Most people should always run "apt-get dist-upgrade" and never "apt-get upgrade" in order to simply keep their packages up-to-date. An actual distribution upgrade is triggered by a different command. On Ubuntu: do-release-upgrade
