To Upgrade

Apt-Get

1. Open up a terminal
2. sudo gedit /etc/apt/sources.list
3. Replace with the following:

## Major bug fix updates produced after the final release of the
## distribution.
deb http://archive.ubuntu.com/ubuntu breezy-updates main restricted
deb-src http://archive.ubuntu.com/ubuntu breezy-updates main restricted

## Uncomment the following two lines to add software from the 'universe'
## repository.

## team, and may not be under a free licence. Please satisfy yourself as to
## your rights to use the software. Also, please note that software in

deb http://archive.ubuntu.com/ubuntu breezy universe multiverse restricted
deb-src http://archive.ubuntu.com/ubuntu breezy universe multiverse restricted

deb http://security.ubuntu.com/ubuntu breezy-security main restricted
deb-src http://security.ubuntu.com/ubuntu breezy-security main restricted

deb http://security.ubuntu.com/ubuntu breezy-security universe

1. sudo apt-get update
2. sudo apt-get dist-upgrade

Post-Upgrade

1. It is recommended that you install the ubuntu-base and ubuntu-desktop metapackages in order to ensure that you have the full set of default packages. Note that without these metapackages it is much more likely that you will encounter problems during the upgrade.

   sudo apt-get install ubuntu-base ubuntu-desktop

2. Reboot in order to effect all changes (XFree86 to X.org, kernel upgrade, etc.)
