I encountered an issue while trying to install the Submarine firmware on SITL. I have a Raspberry Pi 3B+ without a Navigator nor PixHawk. I entered Pirate Mode, and performed a change board to SITL, which worked fine. However, when I clicked to install the Submarine firmware, an error occurred. Despite the error, everything was functioning normally.
