There are thousands of programs available to install on Xubuntu. These programs are stored in software repositories and are made freely available for all Xubuntu users. This makes it very easy to install new programs, and it is also very secure because each program you install is built specially for Xubuntu and checked before it is allowed into the repositories.

Be careful when installing software from third-party repositories. It may not have been tested with Xubuntu and could cause your system to break.

You should be warned by the package manager when you try to install restricted software. If the restricted software cannot be used legally in your country then there is little you can do; you should not install the software. If the software is restricted simply because it is non-free, you may choose to use it (for example, in the case of graphics card drivers). Be aware that most restricted software is not supported in Xubuntu, and problems with such software often cannot be corrected by Xubuntu developers.

When you click <guibutton>Apply Changes</guibutton>, any new software will be downloaded from the Internet, and Xubuntu will make any other changes you selected. If you have not activated the online package archive, you may be asked to insert your Xubuntu CD-ROM to install some packages.

Other than using tools that download packages automatically, it is also possible to use a CD to install packages through a package manager while not connected to the Internet. The Xubuntu installation CD can be used for this purpose, and other CDs with different packages are available as well. Additionally, the program <application>APTonCD</application> can automatically backup installed packages on your system, and create CDs with the contents of various repositories on them.
