Ros foxy with ubuntu focal (20.04)

[olmerg]

There is some provision to support ubuntu 20.04 with ros foxy?

[dusty-nv]

JetPack is on Ubuntu 18.04, so ROS Foxy is built from source in the container so it runs on 18.04.

@dusty-nv is there a date for Ubuntu 20.04 on Jetson? Ubuntu 18.04 is a big limitation now...

[dusty-nv]

Not currently, but you can build these for 18.04, even outside of the containers by following the same procedure in the dockerfiles.

Thank you for your great Dockerfile. I succeeded to build foxy on Jetpack 4.4 and succeeded to run simple pub sub program. But I try to install ros-foxy-turtlesim , I got error as below. apt update apt install ros-foxy-turtlesim --> E: Unable to locate package ros-foxy-turtlesim It's seem to occur at installing any ros-foxy-xxxxx. I think the reason for this is that the apt repository is set to bionic (18.04). I change bionic to focal in /etc/apt/sources.list.d/ros2-latest.list and retry to install, but I got error related to dependencies.

Is there any workaround this issue?

You need to build these packages from source as opposed to trying to install them from apt, because they aren't built for 18.04. The container builds ROS2 Foxy core/base from source.

Thank you for your answer. I understand the reason for the error. It's hard for me to build a any package for foxy, so I'll use eloquent until the 20.04 based jetpack is released.
