I also experienced this bug, in exactly the same situation (upgrading
from 2.2r6 to 3.0r0 with the official CD set), and found a workaround
that worked for me. I posted a description of the workaround to
debian-user, which is archived at:
http://lists.debian.org/debian-user/2002/debian-user-200208/msg01901.html
Basically I first ran "apt-get install dpkg", then "apt-get install
apt", then reran dselect.
Hopefully the nature of the workaround will shed some light on what can
be done to fix the bug?
Thanks,
Nicholas Weininger
