| == Introduction == There are several methods to install software on Ubuntu: * '''Add Applications''', which can be found in the ''Applications'' menu, and the ''System'' > ''Administration'' menu. * '''Synaptic Package Manager''', which can be found in the ''System'' > ''Administration'' menu. * '''apt-get''', which is a terminal application. * '''dpkg''', for installing downloaded .deb files. ''Add Applications'', ''Synaptic Package Manager'' and ''apt-get'' are all different interfaces to ''APT'', the ''Advanced Package Tool''. They all use the same application database. ''APT'' in itself is a front-end to ''dpkg'', the Debian package management system. == APT == APT maintains a list of ''repositories'', on-line software collections. Using one of the interfaces to APT, one can search through the repositories for applications to install. The default Ubuntu repositories already contain over 10,000 applications and packages. === Adding repositories === Sometimes the default repositories are not enough. In these cases, extra repositories can be added to the APT database. You will often find information on repositories in the following format: {{{ deb <url> <component-list>}}} You can add a repository in one of the following ways: * In ''Add Applications'' via ''Settings'' > ''Repositories'' > ''Add'' > ''Custom''. Enter the supplied repository line here. * In ''Synaptic'' via the same menus as in ''Add Applications''. * By manually editing /etc/apt/sources.list. You will need superuser privileges for this, and please make a backup before editing. Just paste the repository line at the end of the file. (Add something about Main, Restricted, Universe, Multiverse, free, non-free, etc.) === Dependencies === Most of the time, the functionality of an application depends on the availability of another package. When installing an application, APT will take care of also installing all ''dependants''. === See also === http://en.wikipedia.org/wiki/Advanced_Packaging_Tool == dpkg == To install a downloaded .deb file, use the following command:{{{ dpkg -i <filename>.deb}}} You will need superuser privileges to do this.
