For all of you who have been bitten by this problem, here is your quickie solution.
Go to http://blevins.simplenet.com/foobar/ Download the .debs there, and upgrade/downgrade to these versions using dpkg (which should still work). I would put these packages on hold for a few days til the problem gets fixed on your mirrors. After you are feeling adventurous, take them off hold. If this breaks things again, go back to foobar and: download rinse repeat. Individual packages (not dselect/apt/dpkg) may or may not still work, but at least you've still got dselect. :( Read the discussion on debian-devel for more info on the problem and for status updates. -Mitch
