Ehm, the above does sound much more simple than this script:

Citing from the URL above:

> apt-get update
> apt-get -y upgrade
> aptitude -y upgrade
> apt-get -y dist-upgrade
> aptitude -y dist-upgrade
> apt-get -y autoremove

Why in the world would someone use apt-get and aptitude alternately
during a dist-upgrade? If you don't want to interfere with, you use
apt-get (which should choose systemd-sysv) or you use aptitude because
you want to interfere and interactively fine-tune aptitude's decisions
anyway, so it shouldn't matter if aptitude chooses the one or the
other because you're going to fine tune such stuff anyways.

See the discussion starting at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=756816#10 for a
discussion about the fundamental differences in the approaches of and
ideas behind apt-get and aptitude.
