Ok, I understand now. However, this has nothing to do with my explanation of dist-upgrade. Consider this situation: Currently stable (wheezy) has: Package: linux-image-<flavour> Depends: linux-image-3.2.0-4-<flavour> Now imagine a severe security bug is found in the kernel and the fix requires an increase in the ABI version[1]. Stable would then have: Package: linux-image-<flavour> Depends: linux-image-3.2.0-5-<flavour> Because the linux-image-3.2.0-5-<flavour> package is not installed 'apt-get upgrade' will not be able to upgrade linux-image-<flavour> and you have to use 'dist-upgrade'. [1] IIRC something like this already happened during the lifetime of squeeze. > IIRC for Debian it's called "lock package" by Synaptic, I don't remember > how it's called by apt, but Google does help: I find it unfortunate that Synaptic Author(s) did not stick to the same wording as apt/itude/dpkg.
