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.

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).

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 4.0.3, 6 August 2008<br> -<br> -Authors are listed at <a href="ch-faqinfo.en.html#s-authors">Debian FAQ Authors</a><br> -<br> -</address> -<hr> - -</body> - -</html> - |
