Adding extra repositories to Ubuntu Karmic
This guide is probably one of the first, most essential things to do to any Ubuntu install. This is specifically for Ubuntu Karmic, but can be used as a reference point for other versions.
The Graphical Way:
- Go to System => Administration => Synaptic Package Manager => Settings => Reposotories
- Here you can select which sources are to be used. You can also manually add sources here.
The Command Line Way (Easier IMO):
- First off, open a console, and make a backup of your current sources file
- Then you can open the sources file to be edited
- Now you can add new sources in the editor that pop’s up. Below is a copy of my sources file.
- Finally in a console perform
sudo cp -i /etc/apt/sources.list /etc/apt/sources.list_backup
sudo gedit /etc/apt/sources.list

Be sure to save the file and return to the console.
*Note: My sources file contains sources that require keys to work correctly. Read below to learn how to Add Reposotory Keys.
sudo apt-get update
And you now should have successfully added new software sources.
Adding Repository Keys:
If you copied my sources list, or are planning to use the mediabuntu, or google repo’s you will need to add keys to your sources list.
To add mediabuntu key
wget –quiet http://packages.medibuntu.org/medibuntu-key.gpg -O – | sudo apt-key add –
To add Google Key:
wget –quiet http://dl.google.com/linux/linux_signing_key.pub -O – | sudo apt-key add –
