7233 msgid "Anatomy of the Package System"
7239 "The Debian packaging system has a large amount of information associated "
7240 "with each package to help assure that it integrates cleanly and easily into "
7241 "the system. The most prominent of its features is the dependency system."
7247 "The dependency system allows individual programs to make use of shared "
7248 "elements in the system such as libraries. It simplifies placing infrequently "
7249 "used portions of a program in separate packages to reduce the number of "
7250 "things the average user is required to install. Also, it allows for choices "
7251 "in mail transport agents, X servers and so on."
7257 "The first step to understanding the dependency system is to grasp the "
7258 "concept of a simple dependency. The meaning of a simple dependency is that a "
7259 "package requires another package to be installed at the same time to work "
7266 "For instance, mailcrypt is an emacs extension that aids in encrypting email "
7267 "with GPG. Without GPGP installed mailcrypt is useless, so mailcrypt has a "
7268 "simple dependency on GPG. Also, because it is an emacs extension it has a "
7269 "simple dependency on emacs, without emacs it is completely useless."
7275 "The other important dependency to understand is a conflicting dependency. It "
7276 "means that a package, when installed with another package, will not work and "
7277 "may possibly be extremely harmful to the system. As an example consider a "
7278 "mail transport agent such as sendmail, exim or qmail. It is not possible to "
7279 "have two mail transport agents installed because both need to listen to the "
7280 "network to receive mail. Attempting to install two will seriously damage the "
7281 "system so all mail transport agents have a conflicting dependency with all "
7282 "other mail transport agents."
7288 "As an added complication there is the possibility for a package to pretend "
7289 "to be another package. Consider that exim and sendmail for many intents are "
7290 "identical, they both deliver mail and understand a common interface. Hence, "
7291 "the package system has a way for them to declare that they are both "
7292 "mail-transport-agents. So, exim and sendmail both declare that they provide "
7293 "a mail-transport-agent and other packages that need a mail transport agent "
7294 "depend on mail-transport-agent. This can add a great deal of confusion when "
7295 "trying to manually fix packages."
7301 "At any given time a single dependency may be met by packages that are "
7302 "already installed or it may not be. APT attempts to help resolve dependency "
7303 "issues by providing a number of automatic algorithms that help in selecting "
7304 "packages for installation."
7310 "<prgn>apt-get</prgn> provides a simple way to install packages from the "
7311 "command line. Unlike <prgn>dpkg</prgn>, <prgn>apt-get</prgn> does not "
7312 "understand .deb files, it works with the package's proper name and can only "
7313 "install .deb archives from a <em>Source</em>."
7319 "The first <footnote><p>If you are using an http proxy server you must set "
7320 "the http_proxy environment variable first, see "
7321 "sources.list(5)</p></footnote> thing that should be done before using "
7322 "<prgn>apt-get</prgn> is to fetch the package lists from the <em>Sources</em> "
7323 "so that it knows what packages are available. This is done with <tt>apt-get "

7346 "Upgrade will attempt to gently upgrade the whole system. Upgrade will never "
7347 "install a new package or remove an existing package, nor will it ever "
7348 "upgrade a package that might cause some other package to break. This can be "
7349 "used daily to relatively safely upgrade the system. Upgrade will list all of "
7350 "the packages that it could not upgrade, this usually means that they depend "
7351 "on new packages or conflict with some other package. <prgn>dselect</prgn> or "
7352 "<tt>apt-get install</tt> can be used to force these packages to install."
7358 "Install is used to install packages by name. The package is automatically "
7359 "fetched and installed. This can be useful if you already know the name of "
7360 "the package to install and do not want to go into a GUI to select it. Any "
7361 "number of packages may be passed to install, they will all be "
7362 "fetched. Install automatically attempts to resolve dependency problems with "
7363 "the listed packages and will print a summary and ask for confirmation if "
7364 "anything other than its arguments are changed."
7370 "Dist-upgrade is a complete upgrader designed to simplify upgrading between "
7371 "releases of Debian. It uses a sophisticated algorithm to determine the best "
7372 "set of packages to install, upgrade and remove to get as much of the system "
7373 "to the newest release. In some situations it may be desired to use "
7374 "dist-upgrade rather than spend the time manually resolving dependencies in "
7375 "<prgn>dselect</prgn>. Once dist-upgrade has completed then "
7376 "<prgn>dselect</prgn> can be used to install any packages that may have been "

7392 "option is <tt>-d</tt> which does not install the fetched files. If the "

7878 "downloaded. For archives it will contain the name of the package that is "

7886 "of the negotiation phase of the download. Typically it progresses from "
7887 "<em>Connecting</em> to <em>Waiting for file</em> to <em>Downloading</em> or "

7961 "Normally APT requires direct access to a Debian archive, either from a local "
7962 "media or through a network. Another common complaint is that a Debian "
7963 "machine is on a slow link, such as a modem and another machine has a very "
7964 "fast connection but they are physically distant."
7970 "The solution to this is to use large removable media such as a Zip disc or a "
7971 "SuperDisk disc. These discs are not large enough to store the entire Debian "
7972 "archive but can easily fit a subset large enough for most users. The idea is "
7973 "to use APT to generate a list of packages that are required and then fetch "
7974 "them onto the disc using another machine with good connectivity. It is even "
7975 "possible to use another Debian machine with APT or to use a completely "
7976 "different OS and a download tool like wget. Let <em>remote host</em> mean "
7977 "the machine downloading the packages, and <em>target host</em> the one with "
7978 "bad or no connection."
7984 "This is achieved by creatively manipulating the APT configuration file. The "
7985 "essential premise to tell APT to look on a disc for it's archive files. Note "
7986 "that the disc should be formated with a filesystem that can handle long file "
7987 "names such as ext2, fat32 or vfat."

7998 "APT being available on both machines gives the simplest configuration. The "
7999 "basic idea is to place a copy of the status file on the disc and use the "
8000 "remote machine to fetch the latest package files and decide which packages "

8020 msgid "The configuration file"
8026 "The configuration file should tell APT to store its files on the disc and to "

8029 "the status file should be a copy of <em>/var/lib/dpkg/status</em> from the "
8030 "<em>target host</em>. Please note, if you are using a local archive you must "
8031 "use copy URIs, the syntax is identical to file URIs."

8081 "On the target machine the first thing to do is mount the disc and copy "
8082 "<em>/var/lib/dpkg/status</em> to it. You will also need to create the "
8083 "directories outlined in the Overview, <em>archives/partial/</em> and "
8084 "<em>lists/partial/</em>. Then take the disc to the remote machine and "
8085 "configure the sources.list. On the remote machine execute the following:"
8088 #. type: <example></example>
8092 " # export APT_CONFIG=\"/disc/apt.conf\"\n"

8102 "The dist-upgrade command can be replaced with any other standard APT "
8103 "commands, particularly dselect-upgrade. You can even use an APT front end "
8104 "such as <em>dselect</em>. However this presents a problem in communicating "
8105 "your selections back to the local computer."
8108 #. type: <p><example>
8111 "Now the disc contains all of the index files and archives needed to upgrade "
8112 "the target machine. Take the disc back and run:"

8119 " # export APT_CONFIG=\"/disc/apt.conf\"\n"

8122 " # apt-get --no-d -o dir::state::status=/var/lib/dpkg/status dist-upgrade\n"
8123 " [ Or any other APT command ]"
8129 "It is necessary for proper function to re-specify the status file to be the "

8136 "If you are using dselect you can do the very risky operation of copying "
8137 "disc/status to /var/lib/dpkg/status so that any selections you made on the "
8138 "remote machine are updated. I highly recommend that people only make "
