samba - May 2011 - Source for latest Samba builds packaged for Ubuntu 10.04 Lucid

Greetings,

When Samba 3 first came out, I made use of the official Debian (Sarge)
repository hosted at samba.org to get access to the very latest Samba builds.

Since switching to Ubuntu, I have sort of lost touch with latest Samba
developments as I have not found an equivalent source for packages.

Currently I have a bug open against Samba on Ubuntu 10.04 Lucid:

"Samba in Lucid upgrade killed Envelope Feeder on HP LJ4000 printer"
https://bugs.launchpad.net/bugs/709188

So that raises the desire to search for a source for Ubuntu packages so I may
evaluate higher versions of Samba. The upgrade from 9.04 to 10.04 introduced
this bug. My thought is trying Samba higher
than what 10.04 ships with might have resolved the problem.

Over the years I have heard of Ubuntu developers which host Samba repos in their
PPA accounts. Is that the best source? If so, which one of the developers? A
link please?

Thanks!
