Bob, can you post your sources.list?
Last time I ran into this, debian, the twit had installed one version,
added some unstable, installed some downloaded source instead of from
repository, and upgraded to testing. And debian had bumped up a
version in the meantime. It was a mess.
Ubuntu is different, non-free, backport, etc., vs stable / testing /
unstable, but similar could be part of the problem.
Things like apt-cache show or apt-cache showpkg may give you a clue.
OTOH, aptitude may well show you the same in a more user friendly manner.
A little more extreme, comment out or take out non-free, etc., long
enough to see just which one is causing you grief - either is bringing
in a newer version than the others, or, you're already at a higher
version than is available in the repository. (The latter is what
caused most of the grief, above.)
