upgrade-system - Command for upgrading and sanitizing a Debian 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:
|o||Synchronize the list of available Debian packages.|
|o||Upgrade all installed packages to their newest versions.|
|o||Recursively uninstall all obsolete package dependencies.|
|o||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.
