How to Add Repositories in Ubuntu

This section describes how to manage software repositories in the currently supported Ubuntu releases: Ubuntu 8.04 (Hardy Heron), Ubuntu 9.04 (Jaunty Jackalope), Ubuntu 9.10 (Karmic Koala), Ubuntu 10.04 (Lucid Lynx) and Ubuntu 10.10 (Maverick Meerkat). For Kubuntu please see Kubuntu repository management.

• The operations described on this page modify the software repositories configuration file located at

  /etc/apt/sources.list 

Software sources can also be managed by making direct modifications to this file using the command line. If you prefer to use the command line instead of a graphical user interface, see Managing Repositories from the Command Line instead.

GUI-based repository management is normally accomplished via "Software Sources". This interface can be accessed via several methods, depending on your version of Ubuntu:

• Main Menu: System > Administration > Software Sources.
• Synaptic : System > Administration > Synaptic Package Manager : >> Settings >> Repositories.
• Main Menu: Ubuntu Software Center : >> Edit, Software Sources.
• You will have to enter your password to gain access to the page.
