Ubuntu is a great oper­at­ing sys­tem, but it does not include all the Linux or open source pro­grams and games you might want. You must install them manually if you need or want them. One of the places where you can download cool open source software for Linux not already installed in Ubuntu is GetDeb (getdeb.net). The open source and freeware software packages available on GetDeb are easy to install.

Before you can install software from GetDeb, you need to add the repository GPG key for GetDeb. To do this, open a Terminal window by selecting Accessories | Terminal from the Applications menu.

Opening a Terminal window

Enter the following command at the prompt. Enter your password when prompted.

wget -q -O- http://archive.getdeb.net/getdeb-archive.key | sudo apt-key add -

NOTE: There is a single dash at the end of the command above. All the other dashes are also single dashes.

When the command has been executed, you should see “OK” display. Enter exit to close the Terminal window.

Getting the GPG key for getdeb.net

Now, you need to add the GetDeb package managers and the software sources for the apps and games. Select Ubuntu Software Center from the Applications menu.

Opening Ubuntu Software Center

The Ubuntu Software Center dialog box displays. Select Software Sources from the Edit menu.

Editing Software Sources

The Software Sources dialog box displays. Click the Other Software tab and click the Add button.

Software Sources dialog box - Add button on Other Software tab

A dialog box displays requesting the complete APT line to add as source. Enter the following line in the APT line edit box and click Add Source.

ppa:getdeb-package-managers/ppa

Adding the getdeb package managers

Add the following two sources also in the same way, using the Add button on the Other Software tab on the Software Sources dialog box, to add the sources for the applications and games from GetDeb.

deb http://archive.getdeb.net/ubuntu lucid-getdeb apps

deb http://archive.getdeb.net/ubuntu lucid-getdeb games

The first source list adds applications that are not games. The sec­ond source list adds games from Play­Deb. Play­Deb is part of GetDeb, and they have many popular games for Ubuntu.

Once you have added all three sources, click Close.

A new menu item called GetDeb displays under Get Software in the tree on the left.

For this example, we selected to install Ailurus, which is a simple application installer and Gnome tweaker. It also provides you with Ubuntu enhancement tricks. Select the desired application and click the Install button that becomes available.

Now, you can browse through applications available on Getdeb through the Ubuntu Software Center and easily install them. To update the repositories so you can make sure you have the latest offerings, open a Terminal window and enter “sudo apt-get update” (without the quotes) at the command prompt.
