4.3.1. Installere tilleggsprogramvare

The installed packages correspond to the profiles selected during installation, but not necessarily to the use that will actually be made of the machine. As such, you might want to use a package management tool to refine the selection of installed packages. The two most frequently used tools (which are installed if the “Debian desktop environment” profile was chosen) are apt (accessible from the command line) and synaptic (“Synaptic Package Manager” in the menus).
To facilitate the installation of coherent groups of programs, Debian creates “tasks” that are dedicated to specific uses (mail server, file server, etc.). You already had the opportunity to select them during installation, and you can access them again thanks to package management tools such as aptitude (the tasks are listed in a distinct section) and synaptic (through the menu EditMark Packages by Task…).
Aptitude is an interface to APT in full-screen text mode. It allows the user to browse the list of available packages according to various categories (installed or not-installed packages, by task, by section, etc.), and to view all of the information available on each of them (dependencies, conflicts, description, etc.). Each package can be marked “install” (to be installed, + key) or “remove” (to be removed, - key). All of these operations will be conducted simultaneously once you've confirmed them by pressing the g key (“g” for “go!”). If you have forgotten some programs, no worries; you will be able to run aptitude again once the initial installation has been completed.
Selvfølgelig er det mulig å ikke installere en hvilken som helst oppgave. I dette tilfellet kan du manuelt installere ønsket programvare med apt-get, eller aptitude-kommandoen (som begge er tilgjengelig fra kommandolinjen).

4.3.2. Å oppgradere systemet

A first aptitude safe-upgrade (a command used to automatically update installed programs) is generally required, especially for possible security updates issued since the release of the latest Debian stable version. These updates may involve some additional questions through debconf, the standard Debian configuration tool. For further information on these updates conducted by aptitude, please refer to Seksjon 6.2.3, «Oppgradering av systemet».
