dselect is a front-end to dpkg
that is used to manage software packages in Debian and Debian-based
Linux distributions. You can use dselect to install packages on your
system from the APT archives defined in /etc/apt/sources.list, review the already installed packages, uninstall and upgrade packages.
dselect has a text-mode user interface that is started after running the dselect command:
dselect will guide you through the package installation through a series of steps:
Access – Choose the access method to use
Update – Update list of available packages, if possible
Select – Request which packages you want on your system
Install – Install and upgrade wanted packages
Config – Configure any packages that are unconfigured
Remove – Remove unwanted software
As each step is completed successfully it will lead you on to the next. Go through them in order without skipping any steps.
Here is a brief description of each step.
Access – Choose the access method to use
First, you need to tell dselect where the packages are. For example, if you are installing packages from a CD-ROM, you would select the cdrom access method, as seen in the picture below:
To update list of available packages, select the Update option. dselect will read the Packages or Packages.gz files from the mirror and create a database of all available packages.
Select – Request which packages you want on your system
To choose which packages you wish to have installed, select the Select option. Here you can mark packages for installation or deinstallation.
Install – Install and upgrade wanted packages
Select this option to install the packages marked in the previous step.
Config – Configure any packages that are unconfigured
Most packages are configured in step 3, but any unconfigured package can be configured here.
Remove – Remove unwanted software
This option removes packages that are installed but no longer required.
