So you had important error messages displayed. :-)

dpkg's --set-selections behaviour has changed and prior to the
--set-selections call, you should make sure that dpkg knows about
all the available packages.

You can use "dselect update" (of dselect) or "sync-available" (of
dctrl-tools) or directly "apt-cache dumpavail | sudo dpkg --update-avail"
to do this.

See http://lists.debian.org/20120319083527.GA4526@gaara.hadrons.org for
the discussion between me and the other dpkg maintainer on this topic.
