if you really want to do this, you also should configure pin priorities
in /etc/apt/preferences (man 5 apt_preferences ; give a pin priority >=
1001 to debian and a very low priority to ubuntu) and have temporarilly
both ubuntu and debian in sources.list; at the end of the upgrade (which
could, and possibly should, be done in stages: first the
required/essential packages, then global upgrade, then dist-upgrade)
when no more ubuntu packages are installed, you can (and possibly
should) remove ubuntu from sources.list and preferences
This is like the _unsupported_ (but often working, if you are able to
manually correct errors that can sometimes slip in) downgrading
procedure:
Linkname: apt preferences pin downgrade - Google Search
URL:
http://www.google.com/search?q=apt+preferences+pin+downgrade&num=100
Linkname: Downgrading Debian
URL: http://people.debian.org/~osamu/downgrade.html
and so on. Look for possible problems and decide yourself (I never had
used Ubuntu, but in the past I did with no real pain downgrades from
sarge/testing to woody/stable and one time from etch/testing to
sarge/stable).
