Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 12.10
Ubuntu 12.04
Ubuntu 11.10
Ubuntu 10.04

After a standard system update you need to restart any applications that
use NSS, such as Evolution and Chromium, to make all the necessary
changes.
