       sources.list - Package resource list for APT

       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 in .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 given distribution, distribution part points to a given
       distribution 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 archecture of the system.

       $(VERSION) is substituted with the distribution version if configured
       automatically via Apt::DistroVerPkg or manually via Apt::DistroVersion
       configuration option.

       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 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

       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
       repositories. Rpm-dir and rpm-src-dir only accept file:// uri's!

       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 an
              environment variable http_proxy 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

       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.


       ssh    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
              find and dd commands to perform the file transfers from the

       Repomd entries for Fedora Core, Extras and Updates using variable
       substitution, assumes Apt::DistroVerPkg is set to "fedora-release":

          repomd fedora/linux/core/$(VERSION)/$(ARCH)/os/
          repomd fedora/linux/extras/$(VERSION)/$(ARCH)/
          repomd fedora/linux/core/updates/$(VERSION)/$(ARCH)/

       Local mirror (local disk, NFS mounted etc) of Fedora Core at

          repomd file:/var/www/html fedora/linux/core/$(VERSION)/$(ARCH)/
