  As I said below, aptitude will break holds to upgrade packages. There isn't much I can do about this as long as I'm relying on core apt code to do the "instant recursive upgrades". There are enough bugs due to apt not behaving the way I like that I'd write my own version of its code full of new and exciting bugs if I had the time, but I don't.

  It would be interesting to know what's pulling in tetex-extra. If you held back all the packages that require it, you could pull off a partial upgrade. It looks like most of the packages that requires tetex-extra are TeX-related, like latex2html, although ocamlweb also shows up.

  I don't know how the TeX team are managing their transition offhand. A start would be to figure out which packages are forcing the upgrade of tetex-extra -- you could find this out by, e.g., going into the interactive interface, holding tetex-extra back after the upgrade (manually), and then seeing what breaks.
