UPGRADE-SYSTEM(8)

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.
