I seem to be "stuck" on the 5 month old nginx 1.4.1 on my Ubuntu 13.04. But reading the 13.10 (Saucy Salamander) Ubuntu repo notes, I see it's STILL that version.

So I found this post: http://www.devcu.com/forums/topic/633-upgrade-nginx-to-latest-stable-release-ubuntu-1204/

It says to replace "raring" (or whatever) with the latest release.

But if I look at http://nginx.org/packages/ubuntu/dists/ I see that only raring is the latest.

So, how can I best ensure that I can apt-get update nginx without having to completely remove and re-install?

Thanks!
