Docker as a factory: fixing broken GPU software without touching the OS
January 2026 — when a friend’s astrophotography software broke and the internet said “reinstall Ubuntu”
A friend of mine called me with a problem. She had a new machine with an RTX 5060 Ti, PixInsight installed natively, and BlurXTerminator — a GPU-accelerated AI denoising plugin for astrophotography — completely broken. The plugin requires libtensorflow 2.11 and CUDA 11.8. Ubuntu 24.04 ships with newer versions. Installing the old ones manually breaks other system libraries.
