Sorry about that. I think we need to make it easier to find distro support resources. http://www.winehq.org/download/ubuntu talks about how to download the latest wine-for-ubuntu packages, but doesn't point to the ubuntu-wine mailing list and bug tracker. You can find them at https://launchpad.net/~ubuntu-wine if you squint hard enough. I asked Scott, the Ubuntu maintainer for Wine, when he'll have the final touches on natty's wine support. It sounds like he hopes it will be ready by a week from now; mostly he's just waiting on approvals, iirc.
