You will require administrative access to install and remove software. This is because packages sometimes need to change important system files. See the <link linkend="administrative"><application>Administrative Tasks</application></link> section for more information on administrative access.

<emphasis role="strong">Dependencies</emphasis> are packages which must be installed before certain other packages can be installed. Dependency packages usually contain some files and programs needed by the other packages - for example, a word-processing package may depend on a printing package being installed in order to be able to print documents.

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.

To organise the software, Xubuntu repositories are categorised 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>.
