Details
The guide explains how to run the actual ChatGPT desktop app, which is distributed by OpenAI as a Windows MSIX binary, on Ubuntu Linux. It involves extracting the app logic from the MSIX package, making a few platform-specific patches, and then packaging the app as a .deb installer for Ubuntu. This allows users to get the full feature set and update hooks of the official ChatGPT desktop app, rather than relying on third-party wrappers that load the web version in an Electron container. The patched app has been tested on Ubuntu 26.04 with various kernel and GPU configurations.
