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>.

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.
