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.
