To be fair, some moving parts outside of canonical's work are necessary yet break often. Prominent example: Nvidia drivers. Oh how often have I wiped a system because the precise combination of driver/CUDA/nvcuvid/nvenc and nvidia-docker broke through some freak update. These are the things that often prevent smooth upgrades.
