+
+ <refsect1><title>Description</title>
+ <para>The package resource list is used to locate archives of the package
+ distribution system in use on the system. At this time, this manual page
+ documents only the packaging system used by the Debian GNU/Linux system.
+ This control file is located in <filename>/etc/apt/sources.list</filename></para>
+
+ <para>The source list is designed to support any number of active sources and a
+ variety of source media. The file lists one source per line, with the
+ most preferred source listed first. The format of each line is:
+ <literal>type uri args</literal> The first item, <literal>type</literal>
+ determines the format for <literal>args</literal> <literal>uri</literal> is
+ a Universal Resource Identifier
+ (URI), which is a superset of the more specific and well-known Universal
+ Resource Locator, or URL. The rest of the line can be marked as a comment
+ by using a #.</para>
+ </refsect1>
+
+ <refsect1><title>The deb and deb-src types</title>
+ <para>The <literal>deb</literal> type describes a typical two-level Debian
+ archive, <filename>distribution/component</filename>. Typically,
+ <literal>distribution</literal> is generally one of
+ <literal>stable</literal> <literal>unstable</literal> or
+ <literal>testing</literal> while component is one of <literal>main</literal>
+ <literal>contrib</literal> <literal>non-free</literal> or
+ <literal>non-us</literal> The
+ <literal>deb-src</literal> type describes a debian distribution's source
+ code in the same form as the <literal>deb</literal> type.
+ A <literal>deb-src</literal> line is required to fetch source indexes.</para>
+
+
+ <para>The format for a <filename>sources.list</filename> entry using the
+ <literal>deb</literal> and <literal>deb-src</literal> types are:</para>
+
+ <literallayout>deb uri distribution [component1] [component2] [...]</literallayout>
+
+ <para>The URI for the <literal>deb</literal> type must specify the base of the
+ Debian distribution, from which APT will find the information it needs.
+ <literal>distribution</literal> can specify an exact path, in which case the
+ components must be omitted and <literal>distribution</literal> must end with
+ a slash (/). This is useful for when only a particular sub-section of the
+ archive denoted by the URI is of interest.
+ If <literal>distribution</literal> does not specify an exact path, at least
+ one <literal>component</literal> must be present.</para>
+
+ <para><literal>distribution</literal> may also contain a variable,
+ <literal>$(ARCH)</literal>
+ which expands to the Debian architecture (i386, m68k, powerpc, ...)
+ used on the system. This permits architecture-independent
+ <filename>sources.list</filename> files to be used. In general this is only
+ of interest when specifying an exact path, <literal>APT</literal> will
+ automatically generate a URI with the current architecture otherwise.</para>
+
+ <para>Since only one distribution can be specified per line it may be necessary
+ to have multiple lines for the same URI, if a subset of all available
+ distributions or components at that location is desired.
+ APT will sort the URI list after it has generated a complete set
+ internally, and will collapse multiple references to the same Internet
+ host, for instance, into a single connection, so that it does not
+ inefficiently establish an FTP connection, close it, do something else,
+ and then re-establish a connection to that same host. This feature is
+ useful for accessing busy FTP sites with limits on the number of
+ simultaneous anonymous users. APT also parallelizes connections to
+ different hosts to more effectively deal with sites with low bandwidth.</para>
+
+ <para>It is important to list sources in order of preference, with the most
+ preferred source listed first. Typically this will result in sorting
+ by speed from fastest to slowest (CD-ROM followed by hosts on a local
+ network, followed by distant Internet hosts, for example).</para>
+
+ <para>Some examples:</para>
+ <literallayout>
+deb http://http.us.debian.org/debian stable main contrib non-free
+deb http://http.us.debian.org/debian dists/stable-updates/
+ </literallayout>
+
+ </refsect1>
+
+ <refsect1><title>URI specification</title>
+
+ <para>The currently recognized URI types are cdrom, file, http, and ftp.
+ <variablelist>
+ <varlistentry><term>file</term>
+ <listitem><para>
+ The file scheme allows an arbitrary directory in the file system to be
+ considered an archive. This is useful for NFS mounts and local mirrors or
+ archives.</para></listitem>
+ </varlistentry>
+
+ <varlistentry><term>cdrom</term>
+ <listitem><para>
+ The cdrom scheme allows APT to use a local CDROM drive with media
+ swapping. Use the &apt-cdrom; program to create cdrom entries in the
+ source list.</para></listitem>
+ </varlistentry>
+
+ <varlistentry><term>http</term>
+ <listitem><para>
+ The http scheme specifies an HTTP server for the archive. If an environment
+ variable <envar>http_proxy</envar> is set with the format
+ http://server:port/, the proxy server specified in
+ <envar>http_proxy</envar> will be used. Users of authenticated
+ HTTP/1.1 proxies may use a string of the format
+ http://user:pass@server:port/
+ Note that this is an insecure method of authentication.</para></listitem>
+ </varlistentry>
+
+ <varlistentry><term>ftp</term>
+ <listitem><para>
+ The ftp scheme specifies an FTP server for the archive. APT's FTP behavior
+ is highly configurable; for more information see the
+ &apt-conf; manual page. Please note that a ftp proxy can be specified
+ by using the <envar>ftp_proxy</envar> environment variable. It is possible
+ to specify a http proxy (http proxy servers often understand ftp urls)
+ using this method and ONLY this method. ftp proxies using http specified in
+ the configuration file will be ignored.</para></listitem>
+ </varlistentry>
+
+ <varlistentry><term>copy</term>
+ <listitem><para>
+ The copy scheme is identical to the file scheme except that packages are
+ copied into the cache directory instead of used directly at their location.
+ This is useful for people using a zip disk to copy files around with APT.</para></listitem>
+ </varlistentry>
+
+ <varlistentry><term>rsh</term><term>ssh</term>
+ <listitem><para>
+ The rsh/ssh method invokes rsh/ssh to connect to a remote host
+ as a given user and access the files. No password authentication is
+ possible, prior arrangements with RSA keys or rhosts must have been made.
+ Access to files on the remote uses standard <command>find</command> and
+ <command>dd</command>
+ commands to perform the file transfers from the remote.</para></listitem>
+ </varlistentry>
+ </variablelist>
+ </para>
+ </refsect1>
+
+ <refsect1><title>Examples</title>
+ <para>Uses the archive stored locally (or NFS mounted) at /home/jason/debian
+ for stable/main, stable/contrib, and stable/non-free.</para>
+ <literallayout>deb file:/home/jason/debian stable main contrib non-free</literallayout>
+
+ <para>As above, except this uses the unstable (development) distribution.</para>
+ <literallayout>deb file:/home/jason/debian unstable main contrib non-free</literallayout>
+
+ <para>Source line for the above</para>
+ <literallayout>deb-src file:/home/jason/debian unstable main contrib non-free</literallayout>
+
+ <para>Uses HTTP to access the archive at archive.debian.org, and uses only
+ the hamm/main area.</para>
+ <literallayout>deb http://archive.debian.org/debian-archive hamm main</literallayout>
+
+ <para>Uses FTP to access the archive at ftp.debian.org, under the debian
+ directory, and uses only the stable/contrib area.</para>
+ <literallayout>deb ftp://ftp.debian.org/debian stable contrib</literallayout>
+
+ <para>Uses FTP to access the archive at ftp.debian.org, under the debian
+ directory, and uses only the unstable/contrib area. If this line appears as
+ well as the one in the previous example in <filename>sources.list</filename>.
+ a single FTP session will be used for both resource lines.</para>
+ <literallayout>deb ftp://ftp.debian.org/debian unstable contrib</literallayout>
+
+ <para>Uses HTTP to access the archive at nonus.debian.org, under the
+ debian-non-US directory.</para>
+ <literallayout>deb http://nonus.debian.org/debian-non-US stable/non-US main contrib non-free</literallayout>
+
+ <para>Uses HTTP to access the archive at nonus.debian.org, under the
+ debian-non-US directory, and uses only files found under
+ <filename>unstable/binary-i3866</filename> on i386 machines,
+ <filename>unstable/binary-m68k</filename> on m68k, and so
+ forth for other supported architectures. [Note this example only
+ illustrates how to use the substitution variable; non-us is no longer
+ structured like this]
