DESCRIPTION
The package resource list is used to locate archives of the package
distribution system in use on the system. This control file is located
in /etc/apt/sources.list and additionally any files ending with ".list"
in /etc/apt/sources.list.d are included.
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:
type uri args. The first item, type, determines the format for args.
uri 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 #.
The generic format of sources.list entry is:
type baseuri distribution [component comp2 ...]
Type is one of the types explained below. Baseuri is the URI to the
root of the given distribution. Distribution points to a given distri‐
bution name, version and architecture. The splitting of URI into
baseuri and distribution parts should be done in a way that allows
pointing the baseuri to another mirror without touching distribution.
Some types additionally support a component-entry.
The following variable substitutions are done on sources.list entries:
$(ARCH) is substituted with the base architecture of the system.
$(VERSION) is substituted with the distribution version if configured
automatically via Apt::DistroVerPkg or manually via the Apt::DistroVer‐
sion configuration option.
THE REPOMD AND REPOMD-SRC TYPES
The format of repomd and repomd-src sources.list entries is:
repomd baseuri distribution
repomd-src baseuri distribution
Repomd repositories do not support a concept of "components"!
THE RPM AND RPM-SRC TYPES
The format of rpm and rpm-src sources.list entries is:
rpm baseuri distribution component [comp2 ...]
rpm-src baseuri distribution component [comp2 ...]
At least one component must be specified for rpm and rpm-src reposito‐
ries.
THE RPM-DIR AND RPM-SRC-DIR TYPES
The format of rpm-dir and rpm-src-dir sources.list entries is:
rpm-dir baseuri distribution component [comp2 ...]
rpm-src-dir baseuri distribution component [comp2 ...]
At least one component must be specified for rpm and rpm-src reposito‐
ries. rpm-dir and rpm-src-dir only accept file:// uri's!
URI SPECIFICATION
The currently recognized URI types are cdrom, file, http, and ftp.
file 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.
cdrom The cdrom scheme allows APT to use a local CDROM drive with
media swapping. Use the apt-cdrom(8) program to create cdrom
entries in the source list.
http The http scheme specifies an HTTP server for the archive. If
the "http_proxy" environment variable is set with the format
"http://server:port/", the proxy server specified in
"http_proxy" 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.
ftp The ftp scheme specifies an FTP server for the archive. APT's
FTP behavior is highly configurable; for more information see
the apt.conf(5) manual page. Please note that a ftp proxy can
be specified by using the "ftp_proxy" 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.
copy 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.
rsh See below.
ssh The rsh/ssh method invokes rsh/ssh to connect to a remote host
as a given user and access the files. No password authentica‐
tion is possible, prior arrangements with RSA keys or rhosts
must have been made. Access to files on the remote uses stan‐
dard find(1) and dd(P) commands to perform the file transfers
from the remote.
EXAMPLES
Repomd entries for Fedora Core, Extras and Updates using variable sub‐
stitution, assumes Apt::DistroVerPkg is set to "fedora-release":
repomd http://download.fedora.redhat.com/pub/ fedora/linux/core/$(VERSION)/$(ARCH)/os/
repomd http://download.fedora.redhat.com/pub/ fedora/linux/extras/$(VERSION)/$(ARCH)/
repomd http://download.fedora.redhat.com/pub/ fedora/linux/core/updates/$(VERSION)/$(ARCH)/
Local mirror (local disk, NFS mounted etc) of Fedora Core at
/var/www/html/fedora/
repomd file:/var/www/html fedora/linux/core/$(VERSION)/$(ARCH)/
