Odd dselect/apt/slink behavior?

[Pete Harlan <harlan@pointofchoice.com>]

Hi,

I upgraded from bo to hamm (via cheapbytes's fixed cd_autoup.sh) and
then to slink, installed 'apt', selected it as my dselect method, and
now almost all of my regular packages are in the "Obsolete/local"
category.

I've seen this other times I've done this, and switching back to the
"ftp" method makes everything go back to normal.  What's wrong?  In
addition to most packages being mis-categorized, there are many
missing (e.g., emacs of any flavor, and elm).

My /etc/apt/sources.list file is unmodified, and looks like:

	# Use for a local mirror - remove the ftp1 http lines for the bits
	# your mirror contains.
	# deb file:/your/mirror/here/debian stable main contrib non-free
	# See sources.list(5) for more information, especial
	# Remember that you can only use http, ftp or file URIs
	deb http://ftp1.us.debian.org/debian unstable main contrib non-free
	deb http://non-us.debian.org/debian-non-US unstable non-US

When I've installed freshly from the CD, rather than updating, I
haven't had this problem.

Any suggestions?

Thanks,
