Start in installer.sh at the build-container path and inspect the container step that adds the NVIDIA repository and installs the pinned libnccl-dev and libnccl2 versions. Run ./installer.sh build-container to reproduce the apt downgrade error; done means the container builds successfully without the libnccl version failure.
