The source list
|
||
|
|
/etc/apt/sources\&.list
|
||
|
|
and the files contained in
|
||
|
|
/etc/apt/sources\&.list\&.d/
|
||
|
|
are designed to support any number of active sources and a variety of source media\&. The files list one source per line (one\-line style) or contain multiline stanzas defining one or more sources per stanza (deb822 style), with the most preferred source listed first (in case a single version is available from more than one source)\&. The information available from the configured sources is acquired by
|
||
|
|
\fBapt\-get update\fR
|
||
|
|
(or by an equivalent command from another APT front\-end)\&.
|

.PP
|
||
|
|
The
|
||
|
|
/etc/apt/sources\&.list\&.d
|
||
|
|
directory provides a way to add sources\&.list entries in separate files\&. Two different file formats are allowed as described in the next two sections\&. Filenames need to have either the extension
|
||
|
|
\&.list
|
||
|
|
or
|
||
|
|
\&.sources
|
||
|
|
depending on the contained format\&. The filenames may only contain letters (a\-z and A\-Z), digits (0\-9), underscore (_), hyphen (\-) and period (\&.) characters\&. Otherwise APT will print a notice that it has ignored a file, unless that file matches a pattern in the
|
||
|
|
Dir::Ignore\-Files\-Silently
|
||
|
|
configuration list \- in which case it will be silently ignored\&.
|
||
|
|
.SH "ONE\-LINE\-STYLE FORMAT"
|
||
|
|
.PP
|
||
|
|
Files in this format have the extension
|
||
|
|
\&.list\&. Each line specifying a source starts with a type (e\&.g\&.
|
||
|
|
deb\-src) followed by options and arguments for this type\&. Individual entries cannot be continued onto a following line\&. Empty lines are ignored, and a
|
||
|
|
#
|
||
|
|
character anywhere on a line marks the remainder of that line as a comment\&. Consequently an entry can be disabled by commenting out the entire line\&. If options should be provided they are separated by spaces and all of them together are enclosed by square brackets ([]) included in the line after the type separated from it with a space\&. If an option allows multiple values these are separated from each other with a comma (,)\&. An option name is separated from its value(s) by an equals sign (=)\&. Multivalue options also have
|
||
|
|
\-=
|
||
|
|
and
|
||
|
|
+=
|
||
|
|
as separators, which instead of replacing the default with the given value(s) modify the default value(s) to remove or include the given values\&.
|
||
|
|
.PP
|
||
|
|
This is the traditional format and supported by all apt versions\&. Note that not all options as described below are supported by all apt versions\&. Note also that some older applications parsing this format on their own might not expect to encounter options as they were uncommon before the introduction of multi\-architecture support\&.
|
||
|
|
.SH "DEB822\-STYLE FORMAT"
|
||
|
|
.PP
|
||
|
|
Files in this format have the extension
|
||
|
|
\&.sources\&. The format is similar in syntax to other files used by Debian and its derivatives, such as the metadata files that apt will download from the configured sources or the
|
||
|
|
debian/control
|
||
|
|
file in a Debian source package\&. Individual entries are separated by an empty line; additional empty lines are ignored, and a
|
||
|
|
#
|
||
|
|
character at the start of the line marks the entire line as a comment\&. An entry can hence be disabled by commenting out each line belonging to the stanza, but it is usually easier to add the field "Enabled: no" to the stanza to disable the entry\&. Removing the field or setting it to yes reenables it\&. Options have the same syntax as every other field: A fieldname separated by a colon (:) and optionally spaces from its value(s)\&. Note especially that multiple values are separated by spaces, not by commas as in the one\-line format\&. Multivalue fields like
|
||
|
|
Architectures
|
||
|
|
also have
|
||
|
|
Architectures\-Add
|
||
|
|
and
|
||
|
|
Architectures\-Remove
|
||
|
|
to modify the default value rather than replacing it\&.
|
||
|
|
.PP
|
||
|
|
This is a new format supported by apt itself since version 1\&.1\&. Previous versions ignore such files with a notice message as described earlier\&. It is intended to make this format gradually the default format, deprecating the previously described one\-line\-style format, as it is easier to create, extend and modify for humans and machines alike especially if a lot of sources and/or options are involved\&. Developers who are working with and/or parsing apt sources are highly encouraged to add support for this format and to contact the APT team to coordinate and share this work\&. Users can freely adopt this format already, but may encounter problems with software not supporting the format yet\&.

.SH "THE DEB AND DEB\-SRC TYPES: GENERAL FORMAT"
|

|
|
.PP
|
||
|
|
The
|
||
|
|
deb
|
||
|
|
type references a typical two\-level Debian archive,
|
||
|
|
distribution/component\&. The
|
||
|
|
distribution
|
||
|
|
is generally a suite name like
|
||
|
|
stable
|
||
|
|
or
|
||
|
|
testing
|
||
|
|
or a codename like
|
||
|
|
stretch
|
||
|
|
or
|
||
|
|
buster
|
||
|
|
while component is one of
|
||
|
|
main,
|
||
|
|
contrib
|
||
|
|
or
|
||
|
|
non\-free\&. The
|
||
|
|
deb\-src
|
||
|
|
type references a Debian distribution\*(Aqs source code in the same form as the
|
||
|
|
deb
|
||
|
|
type\&. A
|
||
|
|
deb\-src
|
||
|
|
line is required to fetch source indexes\&.
|

|
|
.PP
|

The format for two one\-line\-style entries using the
|
||
|
|
deb
|
||
|
|
and
|

|

deb\-src

|

types is:

|
|
The URI for the
|
||
|
|
deb
|
||
|
|
type must specify the base of the Debian distribution, from which APT will find the information it needs\&.
|
||
|
|
suite
|
||
|
|
can specify an exact path, in which case the components must be omitted and
|
||
|
|
suite
|
||
|
|
must end with a slash (/)\&. This is useful for the case when only a particular sub\-directory of the archive denoted by the URI is of interest\&. If
|
||
|
|
suite
|
||
|
|
does not specify an exact path, at least one
|
||
|
|
component
|
||
|
|
must be present\&.
|
||
|
|
.PP
|
||
|
|
suite
|
||
|
|
may also contain a variable,
|
||
|
|
$(ARCH)
|
||
|
|
which expands to the Debian architecture (such as
|
||
|
|
amd64
|
||
|
|
or
|
||
|
|
armel) used on the system\&. This permits architecture\-independent
|
||
|
|
sources\&.list
|
||
|
|
files to be used\&. In general this is only of interest when specifying an exact path;
|
||
|
|
APT
|
||
|
|
will automatically generate a URI with the current architecture otherwise\&.
|
||
|
|
.PP
|
||
|
|
Especially in the one\-line\-style format 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 a connection, close it, do something else, and then re\-establish a connection to that same host\&. APT also parallelizes connections to different hosts to more effectively deal with sites with low bandwidth\&.
|
||
|
|
.PP
|
||
|
|
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)\&.
|
||
|
|
.PP
|
||
|
|
As an example, the sources for your distribution could look like this in one\-line\-style format:

Each source entry can have options specified to modify which source is accessed and how data is acquired from it\&. Format, syntax and names of the options vary between the one\-line\-style and deb822\-style formats as described, but they both have the same options available\&. For simplicity we list the deb822 fieldname and provide the one\-line name in brackets\&. Remember that besides setting multivalue options explicitly, there is also the option to modify them based on the default, but we aren\*(Aqt listing those names explicitly here\&.

\fBCheck\-Valid\-Until\fR
|
||
|

(\fBcheck\-valid\-until\fR) is a yes/no value which controls if APT should try to detect replay attacks\&. A repository creator can declare a time until which the data provided in the repository should be considered valid, and if this time is reached, but no new data is provided, the data is considered expired and an error is raised\&. Besides increasing security, as a malicious attacker can\*(Aqt send old data forever to prevent a user from upgrading to a new version, this also helps users identify mirrors which are no longer updated\&. However, some repositories such as historic archives are not updated any more by design, so this check can be disabled by setting this option to
|
||
|
|
no\&. Defaults to the value of configuration option
|
||
|
|
\fBAcquire::Check\-Valid\-Until\fR
|

|
||
|
|
yes\&.
