There is a new revision of this tutorial available for Ubuntu 12.10 (Quantal Quetzal).
The Perfect Desktop - Ubuntu Studio 12.04 - Page 2
3 Update The System
Now it's time to check for updates and install them. This is done using the Update Manager. Start it by clicking the red exclamation mark on the top bar and selecting Show updates (or start the Update Manager under System > Update Manager):
The Update Manager tells you which updates are available (you can click the Check button to refresh the list). Click Install Updates to install them:
After you type in your password the updates are downloaded and installed (this can take a few minutes).
If a new kernel was amongst the updates, a system restart is required to make the changes effective. If this is necessary, you will see a Restart Now button. Click that button to restart the system. (If no restart is required, click the Close button to leave the Update Manager.)
The system is now up-to-date.
4 Inventory Of What We Have So Far

5 Configure Additional Repositories
Some packages like the Adobe Reader are not available in the standard Ubuntu repositories. The easiest way to make such packages available to your system is to add the Medibuntu repository.
First we open a terminal:
Then we edit /etc/apt/sources.list...
gksu gedit /etc/apt/sources.list
... and enable the precise partner and Ubuntu Extras repositories (if they are not already enabled):
Then save the file.
Next we create the file /etc/apt/sources.list.d/opera.list...
gksu gedit /etc/apt/sources.list.d/opera.list
... and add the Opera repository to it:
deb http://deb.opera.com/opera/ stable non-free
To enable the Medibuntu repository, please do the following:
Import the repository:
sudo wget http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list --output-document=/etc/apt/sources.list.d/medibuntu.list
Import the gpg-key and update your package-list:
sudo apt-get update && sudo apt-get install medibuntu-keyring && sudo apt-get update
to make Synaptic display packages from third-party repositories.
