105 <para><command>apt-get</command> is the command-line tool for handling packages, and may be
106 considered the user's "back-end" to other tools using the APT
107 library. Several "front-end" interfaces exist, such as dselect(8),
108 aptitude, synaptic, gnome-apt and wajig.</para>
109
110 <para>Unless the <option>-h</option>, or <option>--help</option> option is given, one of the
111 commands below must be present.</para>

113 <variablelist>
114 <varlistentry><term>update</term>
115 <listitem><para><literal>update</literal> is used to resynchronize the package index files from
116 their sources. The indexes of available packages are fetched from the
117 location(s) specified in <filename>/etc/apt/sources.list</filename>.
118 For example, when using a Debian archive, this command retrieves and
119 scans the <filename>Packages.gz</filename> files, so that information about new
120 and updated packages is available. An <literal>update</literal> should always be
121 performed before an <literal>upgrade</literal> or <literal>dist-upgrade</literal>. Please
122 be aware that the overall progress meter will be incorrect as the size
123 of the package files cannot be known in advance.</para></listitem>

127 <listitem><para><literal>upgrade</literal> is used to install the newest versions of all packages
128 currently installed on the system from the sources enumerated in

130 new versions available are retrieved and upgraded; under no circumstances
131 are currently installed packages removed, or packages not already installed
132 retrieved and installed. New versions of currently installed packages that
133 cannot be upgraded without changing the install status of another package
134 will be left at their current version. An <literal>update</literal> must be
135 performed first so that <command>apt-get</command> knows that new versions of packages are
136 available.</para></listitem>

140 <listitem><para><literal>dselect-upgrade</literal>
141 is used in conjunction with the traditional Debian packaging
142 front-end, &dselect;. <literal>dselect-upgrade</literal>
143 follows the changes made by &dselect; to the <literal>Status</literal>
144 field of available packages, and performs the actions necessary to realize
145 that state (for instance, the removal of old and the installation of new
146 packages).</para></listitem>

149 <varlistentry><term>dist-upgrade</term>
150 <listitem><para><literal>dist-upgrade</literal> in addition to performing the function of
151 <literal>upgrade</literal>, also intelligently handles changing dependencies
152 with new versions of packages; <command>apt-get</command> has a "smart" conflict
153 resolution system, and it will attempt to upgrade the most important
154 packages at the expense of less important ones if necessary.
155 The <filename>/etc/apt/sources.list</filename> file contains a list of locations
156 from which to retrieve desired package files.
157 See also &apt-preferences; for a mechanism for
158 overriding the general settings for individual packages.</para></listitem>

162 <listitem>
163 <para>
164 <literal>install</literal> is followed by one or more
165 packages desired for installation or upgrading.
166 Each package is a package name, not a fully qualified
167 filename (for instance, in a Debian GNU/Linux system,
168 libc6 would be the argument provided, not
169 <literal>libc6_1.9.6-2.deb</literal>). All packages required
170 by the package(s) specified for installation will also
171 be retrieved and installed.
172 The <filename>/etc/apt/sources.list</filename> file is
173 used to locate the desired packages. If a hyphen is
174 appended to the package name (with no intervening space),
175 the identified package will be removed if it is installed.
176 Similarly a plus sign can be used to designate a
177 package to install. These latter features may be used
178 to override decisions made by apt-get's conflict
179 resolution system.

181
182 <para>A specific version of a package can be selected for installation by
183 following the package name with an equals and the version of the package
184 to select. This will cause that version to be located and selected for
185 install. Alternatively a specific distribution can be selected by
186 following the package name with a slash and the version of the
187 distribution or the Archive name (stable, testing, unstable).</para>

190 be used with care.</para>

192 <para>This is also the target to use if you want to upgrade one or
193 more already-installed packages without upgrading every package
194 you have on your system. Unlike the "upgrade" target, which
195 installs the newest version of all currently installed packages,
196 "install" will install the newest version of only the package(s)
197 specified. Simply provide the name of the package(s) you wish
198 to upgrade, and if a newer version is available, it (and its
199 dependencies, as described above) will be downloaded and
200 installed.

229 <listitem><para><literal>source</literal> causes <command>apt-get</command> to fetch source packages. APT
230 will examine the available packages to decide which source package to
231 fetch. It will then find and download into the current directory the
232 newest available version of that source package. Source packages are
233 tracked separately from binary packages via <literal>deb-src</literal> type lines
234 in the &sources-list; file. This probably will mean that you will not
235 get the same source as the package you have installed or as you could
236 install. If the --compile options is specified then the package will be
237 compiled to a binary .deb using dpkg-buildpackage, if --download-only is
238 specified then the source package will not be unpacked.</para>
239
240 <para>A specific source version can be retrieved by postfixing the source name
241 with an equals and then the version to fetch, similar to the mechanism
242 used for the package files. This enables exact matching of the source

244 <literal>APT::Get::Only-Source</literal> option.</para>
