The Ubuntu repositories provide a wide range of applications which can be directly installed from their servers. However, there are many other good applications which are not included in the repositories. GetDeb is a popular service that makes many of these other applications available to install on Ubuntu. Installing an application from GetDeb is easy:
$ wget http://archive.getdeb.net/install_deb/getdeb-repository_0.1-1~getdeb1_all.deb $ sudo dpkg -i getdeb-repository_0.1-1~getdeb1_all.deb
$ sudo apt-get update
apt-get installas usual.
