Nitrux Update Tool System (NUTS) |

Modern C++ rewrite of NUTS with MauiKit UI and PolicyKit integration.

Introduction

We designed the Nitrux Update Tool System utility to update Nitrux OS and to provide a rollback backup option.

Warning

We intended the Nitrux Update Tool System to work exclusively in Nitrux OS; using this utility in other distributions will break them or cause it to stop working. Please do not open issues regarding this use case; they will be closed.

Features

• It creates a backup of the XFS partition using xfsdump and stores it locally.
• Then, it downloads an OTA-style archive and updates the system atomically.
• Rollbacks are handled offline and integrated into the Nitrux ecosystem through the Live session using xfsrestore.

Configuration:

The Nitrux Update Tool System reads the /etc/nuts.conf file to load certain settings.
