<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>distribution</literal> is generally an archivename like
+ <literal>stable</literal> or <literal>testing</literal> or a codename like
+ <literal>&stable-codename;</literal> or <literal>&testing-codename;</literal>
+ while component is one of <literal>main</literal> <literal>contrib</literal> or
+ <literal>non-free</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 is:</para>
- <literallayout>deb uri distribution [component1] [component2] [...]</literallayout>
+ <literallayout>deb [ options ] 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.
simultaneous anonymous users. APT also parallelizes connections to
different hosts to more effectively deal with sites with low bandwidth.</para>
+ <para><literal>options</literal> is always optional and needs to be surounded by
+ square brackets. It can consist of multiple settings in the form
+ <literal><replaceable>setting</replaceable>=<replaceable>value</replaceable></literal>.
+ Multiple settings are separated by spaces. The following settings are supported by APT,
+ note though that unsupported settings will be ignored silently:
+ <itemizedlist><listitem><para><literal>arch=<replaceable>arch1</replaceable>,<replaceable>arch2</replaceable>,…</literal>

+ be downloaded. If this option is not set all architectures defined by the
+ <literal>APT::Architectures</literal> option will be downloaded.</para></listitem>
+ <listitem><para><literal>trusted=yes</literal> can be set to indicate that packages
+ from this source are always authenificated even if the <filename>Release</filename> file
+ is not signed or the signature can't be checked. This disables parts of &apt-secure;
+ and should therefore only be used in a local and trusted context. <literal>trusted=no</literal>
