You only need to use "--download-only" if your internet connection is
shakey our you want to disconnect the line after downloading because you
pay per time-unit and don't have an unlimited plan. Otherwise just omit
the "--download-only" step.

_If_ you need to use "--download-only", then it should occur before the
"upgrade" step, like so:

apt-get update
apt-get install apt dpkg aptitude
apt-get --download-only dist-upgrade
apt-get upgrade
apt-get dist-upgrade

Normally it is safe to also just use only "apt-get dist-upgrade", but
there is no harm in prepending it with an additional "apt-get upgrade"
step.
