Installing Package Sets (Tasks) with Tasksel
Some package sets are too large to be managed practically through meta packages, so tasks have
been created as an alternative. Tasks are installed and removed using the tasksel utility. When run
without any arguments, tasksel presents a menu from which you can select tasks to install or
remove.
Do not install any tasks if you plan to use this system in conjunction with the server
examples in Chapters 24 and 25.
Additional options are available from the command line:
To see a list of known tasks, run tasksel --list-tasks.
To list the packages that are installed by a task, run tasksel --task-packages
.
When a task is removed, all programs associated with that task, whether installed
manually or as part of that task, are removed!
An example of a popular task to install is the desktop task. The desktop task installs three complete
desktop environments based on the X Window System: GNOME, KDE, and XFCE environments.
Note that this task will take a long time to download and install and requires several gigabytes
of disk space to complete. To start the desktop task, run the following:
# tasksel install desktop
Alternatives, Diversions, and Stat Overrides
In cases where there is more than one installed program that provides a specific function, package
maintainers have the option of utilizing Debian??™s alternatives system.
