Software repositories

104.

To organize the software, Ubuntu 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>.

105.

The standard Ubuntu Install CD contains some software from the <emphasis>Main</emphasis> and <emphasis>Restricted</emphasis> categories.

106.

If your system is connected to the Internet, many more software programs are made available for installation. For example, the <quote>Universe</quote> and <quote>Multiverse</quote> repositories are only available over the Internet.

107.

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. When installing each package from this repository, you should verify that the laws of your country permit you to use it. Also, this software may not include security updates.

Update repositories

The Update Manager automatically finds software updates for your computer when they are available. It regularly gathers information on potential updates from a number of online update sources.
