@jaelpark I believe I was wrong, while you don’t have to use buster on rpi4 and can flash any distro you want on it, it seems that Buster is the recommend OS. Operating system images – Raspberry Pi
I tried to install ROS Noetic using Ubuntu Focal repositories, but that didn’t go very well. @acxz how did you manage to install ros-noetic-ros-base as mentioned in PR #6 of the pi-gen-navio repository?
I think that supporting Ubuntu 20.04 (18.04) would be a better fit to run ROS Noetic (Melodic) without Ardupilot stack. In that way, you could have all the precompiled binaries for ROS and things would be a lot easier. You can check out (and support) this forum post regarding that topic
Hello @guido_sanchez, that codebase is to create a Navio image with ros-noetic preinstalled. If you follow that repo’s instructions, instead of trying to remove kinetic and then install noetic from an existing image, it should work.
