Package manager for debian linux

This chapter is written assuming the latest stable release is codename: lenny.

Debian is a volunteer organization which builds consistent distributions of pre-compiled binary packages of free software and distributes them from its archive.

The Debian archive is offered by many remote mirror sites for access through HTTP and FTP methods. It is also available as CD-ROM/DVD.

The Debian package management system, when used properly, offers the user to install consistent sets of binary packages to the system from the archive. Currently, there are 28313 packages available for the amd64 architecture.

The Debian package management system has a rich history and many choices for the front end user program and back end archive access method to be used. Currently, we recommend aptitude(8) as the main front end program for the Debian package management activity.

2.1. Debian package management prerequisites
2.1.1. Package configuration

Here are some key points for package configuration on the Debian system.

* The manual configuration by the system administrator is respected. In other words, the package configuration system makes no intrusive configuration for the sake of convenience.
* Each package comes with its own configuration script with standardized user interface called debconf(7) to help initial installation process of the package.
* Debian Developers try their best to make your upgrade experience flawless with package configuration scripts.
* Full functionalities of packaged software are available to the system administrator. But ones with security risks are disabled in the default installation.
* If you manually activate a service with some security risks, you are responsible for the risk containment.
* Esoteric configuration may be manually enabled by the system administrator. This may creates interference with popular generic helper programs for the system configuration.
