Command for upgrading and sanitizing a debian system
upgrade-system
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.
Setting the FLAUSCH environment variable enables useful advanced system sanitization features. See upgrade-system.conf(5) for more details.
