BEFORE YOU UPGRADE TO POTATO LOOK AT ALL THREADS ON DEVEL PERTAINING TO LIBC6 PROBLEMS.
Sorry about the all caps. ;-) but I believe its in order. There is currently a problem with the libc6 package that the maintainer is working on right now. Libc6 was incoporated into a different package (libc6-bin or something like), which now conflicts with and replaces libc6. Several threads on debian-devel explain the problem more fully. I would always reccomend thoroughly scanning debian-devel for upgrade issues before you "apt-get dist-upgrade" so you don't get bit. -ptw-
