As a security measure, most software repositories use a GPG key to digitally sign the files they provide. This makes it easy to check that the files have not been tampered with since their creation. In order for your package manager 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.

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>.
