Jetpack Ubuntu 20.04

Why is jetpack only supported on Ubuntu 18.04, which in many way is obsolete? Have you decided to skip 20.04 and move directly to 22.04?

Hi @allan7, please see this topic regarding the switch to Ubuntu 20.04 LTS in the planned JetPack 5 release:

Jetson Software Roadmap for 2H-2021 and 2022

NVIDIA continuously invests in JetPack and regularly ships software updates to enable performance improvements, new capabilities, and support for new modules and developer kits. In this announcement, we provide details about the current software roadmap for 2H-2021 and 2022. Note that this plan is subject to change.

These have GPU support enabled and I built the ROS2 packages from source to make them work.

Hi Dusty. Thanks for your reply.

I’ve already used your docker framework, and have tried to build on dustynv/ros: foxy-ros-base-l4t-r32.6.1 to customize it our packages, but I’m drowning in errors when I try to install ROS packages and dependencies. Do you happen to have an image that can run smartmicros umrr_ros2_driver?

You may need to build the packages from source as opposed to installing them via apt.

Here’s an example of building additional packages on top of the ros:foxy-base-l4t container: jetson-containers/Dockerfile.ros.slam at 56bdf7e31037b308b6ef3039175c80a64e5e9d81 · dusty-nv/jetson-containers · GitHub
