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.

14.

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>.

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.

28.

Once you have downloaded the GPG key, import the key by selecting the Authenticate tab, and clicking on <emphasis>Import Key File...</emphasis>, and then selecting the GPG key to be imported.

With the <guimenuitem>Add/Remove…</guimenuitem> item in the <guimenu>Applications</guimenu> menu, you can install programs to do new things with Xubuntu. You can also remove programs you don't want. You need administrative access to use <application>Add/Remove Programs</application> (see <link linkend="root-and-sudo">Administrative Tasks</link> for more details).

When you click <guibutton>Apply</guibutton> or <guibutton>OK</guibutton>, any new software will be downloaded from the Internet, and Xubuntu will make the 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.

Several other package managers exist in Xubuntu. These contain more advanced features than <application>Add/Remove Applications</application>.

To launch <application>Synaptic</application>, from the <guimenu>System</guimenu> menu choose <menuchoice><guimenu>Applications</guimenu><guisubmenu>System</guisubmenu><guimenuitem>Synaptic Package Manager</guimenuitem></menuchoice>. You need administrative access to use <application>Synaptic</application>. See <link linkend="root-and-sudo">Administrative Tasks</link> for more details.

If you are comfortable using the Terminal, you can use <application>apt</application> (Advanced Packaging Tool) to install or remove software. You need administrative access to use <application>apt</application>. See <link linkend="root-and-sudo">Administrative Tasks</link> for more details.

48.

To update the local list of packages, enter in a Terminal: <screen>sudo apt-get update</screen> Note that this command only updates the package <emphasis>information</emphasis> on your system. It does not install or update the actual software packages.
