Another Version of Ubuntu Is Out—How Do I Upgrade my current Ubuntu?

Automatic
-------------
If a new version of Ubuntu is released, the update manager will notify you via an upgrade notification pop-up bubble. To upgrade, click the Upgrade button, and follow the instructions.

Manual
----------
If you want to manually upgrade, first find out the codename for the next version of Ubuntu (in the same vain as Warty, Hoary, Breezy, and Dapper). Now open this file:

/etc/apt/sources.list


and replace the word "dapper" (or the code name of your current ubuntu) with the new codeword. Now run:

sudo apt-get updates


This command updated your package list. Now upgrade the system:

sudo apt-get dist-upgrade


You are asked if you wish to continue. Press Y, and then press Enter to continue. Your entire system is now upgraded.
