TeX Live 2012 is scheduled to be included in Ubuntu 12.10 (Quantal). There is also an offical "backports" PPA for Ubuntu 12.04 (Precise) users. To install/upgrade to TeX Live 2012, follow these steps from the terminal:
1) Add the texlive-backports PPA with the following command:
$ sudo apt-add-repository ppa:texlive-backports/ppa
2) Update your APT package index:

3) Now install TeX Live 2012:

Note: If you already have a previous version of
TeX Live installed, you can use sudo apt-get upgrade
to replace step 3. However this will also update all other packages
on your Ubuntu system.
