This will give you your installed version, the candidate version
that's available (if any), and the sources for the various versions:

apt-cache policy PACKAGENAME

If you're feeling frisky, either of these will probably give you way
more information that you need, but can be good to keep in your back
pocket:

dpkg -s PACKAGENAME

apt-cache showpkg PACKAGENAME
