A package was recently added to Ubuntu. (It was synced from Debian.)
I searched for it on http://packages.ubuntu.com but it isn't showing up.
How long does it take?

will show you all versions in the repositories:
Apparently it's there now.
packages.ubuntu.com for maverick is broken due to a bug which is still in the process of being fixed. It should take only some time to get into Ubuntu. Meanwhile, you can also look at launchpad.net/ubuntu/+source/package-name for example https://launchpad.net/ubuntu/+source/stackapplet
rmadison is another great tool which can help you know the status of a package.

I suspect http://packages.ubuntu.com -- like any ubuntu machine -- only updates every so often so will often lag behind.
If you can't see the package, your local repo might be behind the rest. Try changing to the main repo which should be the first to update.
