Adding Software Repositories to Ubuntu
To make apt-get or “Add applications” show more software, enable more software repostories.
You can make the change in either command line or the graphical user interface, no need to do both.
The Command Line Interface way
Sometimes you need a piece of software that’s not available in the default repositories (main and restricted). For example, apt-cache shows 0 hits for your program:
$ apt-cache search system-config-kickstart $
You can add more repositories with
$ sudo nano /etc/apt/sources.list
deb http://fi.archive.ubuntu.com/ubuntu/ breezy main restricted universe multiverse deb-src http://fi.archive.ubuntu.com/ubuntu/ breezy main restricted universe multiverse deb http://security.ubuntu.com/ubuntu breezy-security main restricted universe multiverse deb-src http://security.ubuntu.com/ubuntu breezy-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ breezy-updates main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu/ breezy-updates main restricted universe multiverse
$ sudo apt-get update
Now apt-get can install a lot more packages, for example:
$ apt-cache search system-config-kickstart system-config-kickstart - graphical tool for creating Kickstart files
