The <emphasis>Multiverse</emphasis> repository contains software which has been classified as <emphasis>non-free</emphasis>. This software may not be permitted in some jurisdictions.

Most of the software available for Xubuntu is free, open-source software. This software is free for anyone to install and use, and people can modify the software and redistribute it if they like. Xubuntu is built from this type of software.

<emphasis role="strong">Restricted software</emphasis> is software which has restrictions on its use, preventing it from being classed as free software. Non-free software is a type of restricted software, where the restrictions are due to the software having a non-free license. Other reasons for software being classed as restricted include legal issues (use of some types of software is illegal in some countries) and patent issues (some software requires a patent license to be used legally).

In some cases, restricted software is the only option. Such cases include software for the playback of certain audio and video formats, some fonts and <link linkend="restricted-manager"><application>drivers for some graphics cards</application></link>.

47.

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.

48.

Sometimes it is difficult to determine why a particular software package is restricted. If this is the case, seek advice on the <ulink url="http://ubuntuforums.org/">Ubuntu Forums</ulink>. If you are still unable to determine why a package is restricted, err on the side of caution and do not install it; it may be illegal to use it in your country.

You need administrative access to use <application>Add/Remove Applications</application> (see <link linkend="administrative"><application>Administrative Tasks</application></link> for more details).
