<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 are:</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.
<literal>distribution</literal> can specify an exact path, in which case the
components must be omitted and <literal>distribution</literal> must end with

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>
+ can be used to specify for which architectures packages information should
+ be downloaded. If this option is not set all architectures defined by the

+ <listitem><para><literal>trusted=yes</literal> can be set to indicate that packages
+ from this source are always authenticated 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>
