Debian

Debian is not a native rosdep/ROS target. It is used as a real-time docker host: a Debian PC provides the PREEMPT_RT kernel and Docker runtime, while ROS itself still runs inside one of the Ubuntu containers from the table above. See Setup Real-Time Kernel (Debian, prebuilt package) for the full setup.
