7226 msgid "Anatomy of the Package System"
7232 "The Debian packaging system has a large amount of information associated "
7233 "with each package to help assure that it integrates cleanly and easily into "
7234 "the system. The most prominent of its features is the dependency system."
7240 "The dependency system allows individual programs to make use of shared "
7241 "elements in the system such as libraries. It simplifies placing infrequently "
7242 "used portions of a program in separate packages to reduce the number of "
7243 "things the average user is required to install. Also, it allows for choices "
7244 "in mail transport agents, X servers and so on."
7250 "The first step to understanding the dependency system is to grasp the "
7251 "concept of a simple dependency. The meaning of a simple dependency is that a "
7252 "package requires another package to be installed at the same time to work "
7259 "For instance, mailcrypt is an emacs extension that aids in encrypting email "
7260 "with GPG. Without GPGP installed mailcrypt is useless, so mailcrypt has a "
7261 "simple dependency on GPG. Also, because it is an emacs extension it has a "
7262 "simple dependency on emacs, without emacs it is completely useless."
7268 "The other important dependency to understand is a conflicting dependency. It "
7269 "means that a package, when installed with another package, will not work and "
7270 "may possibly be extremely harmful to the system. As an example consider a "
7271 "mail transport agent such as sendmail, exim or qmail. It is not possible to "
7272 "have two mail transport agents installed because both need to listen to the "
7273 "network to receive mail. Attempting to install two will seriously damage the "
7274 "system so all mail transport agents have a conflicting dependency with all "
7275 "other mail transport agents."
7281 "As an added complication there is the possibility for a package to pretend "
7282 "to be another package. Consider that exim and sendmail for many intents are "
7283 "identical, they both deliver mail and understand a common interface. Hence, "
7284 "the package system has a way for them to declare that they are both "
7285 "mail-transport-agents. So, exim and sendmail both declare that they provide "
7286 "a mail-transport-agent and other packages that need a mail transport agent "
7287 "depend on mail-transport-agent. This can add a great deal of confusion when "
7288 "trying to manually fix packages."
7294 "At any given time a single dependency may be met by packages that are "
7295 "already installed or it may not be. APT attempts to help resolve dependency "
7296 "issues by providing a number of automatic algorithms that help in selecting "
7297 "packages for installation."
7303 "<prgn>apt-get</prgn> provides a simple way to install packages from the "
7304 "command line. Unlike <prgn>dpkg</prgn>, <prgn>apt-get</prgn> does not "
7305 "understand .deb files, it works with the package's proper name and can only "
7306 "install .deb archives from a <em>Source</em>."
7312 "The first <footnote><p>If you are using an http proxy server you must set "
7313 "the http_proxy environment variable first, see "
7314 "sources.list(5)</p></footnote> thing that should be done before using "
7315 "<prgn>apt-get</prgn> is to fetch the package lists from the <em>Sources</em> "

7344 "on new packages or conflict with some other package. <prgn>dselect</prgn> or "
7345 "<tt>apt-get install</tt> can be used to force these packages to install."
7351 "Install is used to install packages by name. The package is automatically "
7352 "fetched and installed. This can be useful if you already know the name of "
7353 "the package to install and do not want to go into a GUI to select it. Any "
7354 "number of packages may be passed to install, they will all be "
7355 "fetched. Install automatically attempts to resolve dependency problems with "
7356 "the listed packages and will print a summary and ask for confirmation if "
7357 "anything other than its arguments are changed."
7363 "Dist-upgrade is a complete upgrader designed to simplify upgrading between "
7364 "releases of Debian. It uses a sophisticated algorithm to determine the best "
7365 "set of packages to install, upgrade and remove to get as much of the system "
7366 "to the newest release. In some situations it may be desired to use "
7367 "dist-upgrade rather than spend the time manually resolving dependencies in "

7954 "Normally APT requires direct access to a Debian archive, either from a local "
7955 "media or through a network. Another common complaint is that a Debian "
7956 "machine is on a slow link, such as a modem and another machine has a very "
7957 "fast connection but they are physically distant."
7963 "The solution to this is to use large removable media such as a Zip disc or a "
7964 "SuperDisk disc. These discs are not large enough to store the entire Debian "
7965 "archive but can easily fit a subset large enough for most users. The idea is "
7966 "to use APT to generate a list of packages that are required and then fetch "
7967 "them onto the disc using another machine with good connectivity. It is even "
7968 "possible to use another Debian machine with APT or to use a completely "
7969 "different OS and a download tool like wget. Let <em>remote host</em> mean "
7970 "the machine downloading the packages, and <em>target host</em> the one with "
7971 "bad or no connection."
7977 "This is achieved by creatively manipulating the APT configuration file. The "
7978 "essential premise to tell APT to look on a disc for it's archive files. Note "
