This is a modified version of the app posted here by thornydre (Lucas BOUTROT). I replaced the .bat file with a similar shell script and refactored parts of the python script accordingly to make the app run on most Linux distros. Follow INSTALLATION.md to install PySide6 (QT bindings for python 3) if you don't have it installed. If you already have PySide6, just run python blender_updater.py after configuring blender_updater.conf with your git project folder and (optionally) a custom relative build directory.
