Redmine

So I was trying to install some plugins in my Ubuntu 11.04 redmine installation (installed via apt-get) and noticed the version there is kinda old (1.0.5). I know there are guides here on updating redmine but the apt-get installation seems quite different for a LAMP server. It makes some different folders for configuration among other things.

Anyone know a repository with the newest version (as of now 1.2.1 or 1.2)? Or maybe a guide specifically made for apt-get installations?

Thanks in advance!
