NAME

       upgrade-system - Command for upgrading and sanitizing a Debian system

SYNOPSIS

       upgrade-system

DESCRIPTION

       upgrade-system  is  an  APT front-end that simplifies regular upgrading of Debian systems,
       only requiring an administrator's intervention whenever updated packages  necessitate  the
       configuration of new features.

       The command sequentially performs the following operations:

       •  Synchronize the list of available Debian packages.

       •  Upgrade all installed packages to their newest versions.

       •  Recursively uninstall all obsolete package dependencies.

       •  Clean retrieved archives off the APT cache.

ENVIRONMENT

       Setting  the  FLAUSCH  environment  variable  enables  useful advanced system sanitization
       features. See upgrade-system.conf(5) for more details.
