For woody and earlier releases, this was the main package management +interface for for first-time installations, but currently users are encouraged +to use <code>aptitude</code> instead. Some users might feel more comfortable +using <code>aptitude</code> and it is also recommended over +<code>dselect</code> for large-scale upgrades. For more information on +<code>aptitude</code> please see <a href="#s-aptitude">aptitude, Section +8.1.3</a>. +</p> + +<p> +<code>dselect</code> can: +</p> +<ul> +<li> +<p> +guide the user as he/she chooses among packages to install or remove, ensuring +that no packages are installed that conflict with one another, and that all +packages required to make each package work properly are installed; +</p> +</li> +</ul> +<ul> +<li> +<p> +warn the user about inconsistencies or incompatibilities in their selections; +</p> +</li> +</ul> +<ul> +<li> +<p> +determine the order in which the packages must be installed; +</p> +</li> +</ul> +<ul> +<li> +<p> +automatically perform the installation or removal; and +</p> +</li> +</ul> +<ul> +<li> +<p> +guide the user through whatever configuration process are required for each +package. +</p> +</li> +</ul> + +<p> +<code>dselect</code> begins by presenting the user with a menu of 7 items, each +of which is a specific action. The user can select one of the actions by using +the arrow keys to move the highlighter bar, then pressing the +<em><enter></em> key to select the highlighted action. +</p> + +<p> +What the user sees next depends on the action he selected. If he selects any +option but <samp>Access</samp> or <samp>Select</samp>, then +<code>dselect</code> will simply proceed to execute the specified action: e.g., +if the user selected the action <samp>Remove</samp>, then dselect would proceed +to remove all of the files selected for removal when the user last chose the +<samp>Select</samp> action. +</p> + +<p> +Both the <samp>Access</samp> menu item and the <samp>Select</samp> menu item +lead to additional menus. In both cases, the menus are presented as split +screens; the top screen gives a scrollable list of choices, while the bottom +screen gives a brief explanation ("info") for each choice. +</p> + +<p> +Extensive on-line help is available, use the '?' key to get to a help screen +at any time. +</p> + +<p> +The order in which the actions are presented in the first <code>dselect</code> +menu represents the order in which a user would normally choose +<code>dselect</code> to install packages. However, a user can pick any of the +main menu choices as often as needed (including not at all, depending on what +one wants to do). +</p> +<ul> +<li> +<p> +Begin by choosing an <strong>Access Method</strong>. This is the method by +which the user plans on accessing Debian packages; e.g., some users have Debian +packages available on CD-ROM, while others plan to fetch them using anonymous +FTP. The selected "Access Method" is stored after +<code>dselect</code> exits, so if it does not change, then this option need not +be invoked again. +</p> +</li> +</ul> +<ul> +<li> +<p> +Then <strong>Update</strong> the list of available packages. To do this, +<code>dselect</code> reads the file "Packages.gz" which should be +included in the top level of the directory where the Debian packages to be +installed are stored. (But if it is not there, <code>dselect</code> will offer +to make it for you.) +</p> +</li> +</ul> +<ul> +<li> +<p> +<strong>Select</strong> specific packages for installation on his system. +After choosing this menu item, the user is first presented with a full screen +of help (unless the `--expert' command line option was used). Once the user +exits the Help screen, he sees the split-screen menu for choosing packages to +install (or remove). +</p> + +<p> +The top part of the screen is a relatively narrow window into the list of +Debian's 18200 packages; the bottom part of the screen contains description of +the package or group of packages which are highlighted above. +</p> + +<p> +One can specify which packages should be operated on by highlighting a package +name or the label for a group of packages. After that, you can select +packages: +</p> +<dl> +<dt>to be installed:</dt> +<dd> +<p> +This is accomplished by pressing the `+' key. +</p> +</dd> +</dl> +<dl> +<dt>to be deleted:</dt> +<dd> +<p> +Packages can be deleted two ways: +</p> +<ul> +<li> +<p> +removed: this removes most of the files associated with the package, but +preserves the files listed as configuration files (see <a +href="ch-pkg_basics.en.html#s-conffile">What is a Debian conffile?, Section +7.5</a>) and package configuration information. This is done by pressing the +`-' key. +</p> +</li> +</ul> +<ul> +<li> +<p> +purged: this removes <em>every</em> file that is part of the package. This is +done by pressing the `_' key. +</p> +</li> +</ul> + +<p> +Note that it's not possible to remove "All Packages". If you try +that, your system will instead be reduced to the initial installed base +packages. +</p> +</dd> +</dl> +<dl> +<dt>to be put "on hold"</dt> +<dd> +<p> +This is done by pressing `=', and it effectively tells <code>dselect</code> not +to upgrade a package even if the version currently installed on your system is +not as recent as the version that is available in the Debian repository you are +using (this was specified when you set the <strong>Access Method</strong>, and +acquired when you used <strong>Update</strong>). +</p> + +<p> +Just like you can put a package on hold, you can reverse such setting by +pressing `:'. That tells <code>dselect</code> that the package(s) may be +upgraded if a newer version is available. This is the default setting. +</p> +</dd> +</dl> + +<p> +You can select a different order in which the packages are presented, by using +the `o' key to cycle between various options for sorting the packages. The +default order is to present packages by Priority; within each priority, +packages are presented in order of the directory (a.k.a. section) of the +archive in which they are stored. Given this sort order, some packages in +section A (say) may be presented first, followed by some packages in section B, +followed by more packages (of lower priority) in section A. +</p> + +<p> +You can also expand meanings of the labels at the top of the screen, by using +the `v' (verbose) key. This action pushes much of the text that formerly fit +onto the display off to the right. To see it, press the right arrow; to scroll +back to the left, press the left arrow. +</p> + +<p> +If you select a package for installation or removal, e.g., +<code>foo.deb</code>, and that package depends on (or recommends) another +package, e.g., <code>blurf.deb</code>, then <code>dselect</code> will place the +you in a sub-screen of the main selection screen. There you can choose among +the related packages, accepting the suggested actions (to install or not), or +rejecting them. To do the latter, press Shift-D; to return to the former, +press Shift-U. In any case, you can save your selections and return to the +main selection screen by pressing Shift-Q. +</p> +</li> +</ul> +<ul> +<li> +<p> +Users returning to the main menu can then select the "Install" menu +item to unpack and configure the selected packages. Alternatively, users +wishing to remove files can choose the "Remove" menu item. At any +point, users can choose "Quit" to exit dselect; users' selections are +preserved by <code>dselect</code>. +</p> +</li> +</ul> + +<hr> + +<h4><a name="s-dpkg-deb"></a>8.1.6.2 dpkg-deb</h4> + +<p> +This program manipulates Debian archive(<samp>.deb</samp>) files.

How do I make sure old unused library-packages get purged?</h2> + +<p> +Some packages are split in program (`foo') and data (`foo-data') (or in `foo' +and `foo-doc'). This is true for many games, multimedia applications and +dictionaries in Debian and has been introduced since some users might want to +access the raw data without installing the program or because the program can +be run without the data itself, making it optional. +</p> + +<p> +Similar situations occur when dealing with libraries: generally these get +installed since packages containing applications depend on them. When the +application-package is purged, the library-package might stay on the system. +Or: when the application-package no longer depends upon e.g. libdb4.2, but +upon libdb4.3, the libdb4.2 package might stay when the application-package is +upgraded. +</p> + +<p> +In these cases, `foo-data' doesn't depend on `foo', so when you remove the +`foo' package it will not get automatically removed by most package management +tools. The same holds true for the library packages. This is necessary to +avoid circular dependencies. If you use <code>aptitude</code> (see <a +href="#s-aptitude">aptitude, Section 8.1.3</a>) as your package management tool +it will, however, track automatically installed packages and remove them when +no packages remain that need them in your system. +</p> + +<hr> + +<p> +[ <a href="ch-pkg_basics.en.html">previous</a> ] +[ <a href="index.en.html#contents">Contents</a> ] +[ <a href="ch-basic_defs.en.html">1</a> ] +[ <a href="ch-getting.en.html">2</a> ] +[ <a href="ch-choosing.en.html">3</a> ] +[ <a href="ch-compat.en.html">4</a> ] +[ <a href="ch-software.en.html">5</a> ] +[ <a href="ch-ftparchives.en.html">6</a> ] +[ <a href="ch-pkg_basics.en.html">7</a> ] +[ 8 ] +[ <a href="ch-uptodate.en.html">9</a> ] +[ <a href="ch-kernel.en.html">10</a> ] +[ <a href="ch-customizing.en.html">11</a> ] +[ <a href="ch-support.en.html">12</a> ] +[ <a href="ch-contributing.en.html">13</a> ] +[ <a href="ch-redistrib.en.html">14</a> ] +[ <a href="ch-nexttime.en.html">15</a> ] +[ <a href="ch-faqinfo.en.html">16</a> ] +[ <a href="ch-uptodate.en.html">next</a> ] +</p> + +<hr> + +<p> +The Debian GNU/Linux FAQ +</p> + +<address> +version 4.0.4+nmu1, 3 January 2010<br> +<br> +Authors are listed at <a href="ch-faqinfo.en.html#s-authors">Debian FAQ Authors</a><br> +<br> +</address> +<hr> + +</body> + +</html> + |
