There are thousands of programs available to install on Xubuntu. These programs are stored in software archives called (<emphasis>repositories</emphasis>) and are made freely available for installation over the Internet. This makes it very easy to install new programs on your system, and it is also very secure, because each program you install is built specially for Xubuntu and checked before it is installed.

To organize the software, Xubuntu repositories are categorized into four groups: <emphasis>Main</emphasis>, <emphasis>Restricted</emphasis>, <emphasis>Universe</emphasis>, and <emphasis>Multiverse</emphasis>. The rationale used to determine which software goes into which category is based on the level of support that software development teams provide for a program and the level of compliance the program has to the <ulink url="http://www.ubuntu.com/ubuntu/philosophy">Free Software Philosophy</ulink>.

Be careful when installing software from third-party repositories. Software from third-party repositories is not supported by Xubuntu. The software they contain may not have been tested with Xubuntu, and could cause your system to break.

Most software repositories use a GPG key to digitally sign the files they provide, which makes it easy to check that the files haven't been tampered with since their creation. In order for apt to be able to check this, you need the public key that corresponds to the signatures. The key should be available for download on the repository's website.
