You misunderstand, dist-upgrade does not upgrade the release, that is
distribution-upgrade or something similar). apt-get upgrade will install
upgrades to existing installed packages when possible but will not install
new required packages. This can prevent the upgrade of some existing
packages, which is what you are seeing. I can virtually guarantee that
dist-upgrade is what you want.

Look at the docs for apt-get to convince yourself.
