Unable to install navigation2

[adc-zhao]

Hello,

Here is a question about install navigation2.

I built the container successfully on my Jetson, and next I want to install ros-humble-navigation2 and ros-humble-nav2-bringup in docker.
But it shows like below:
root@ubuntu:/workspace# apt-get install ros-humble-navigation2 Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package ros-humble-navigation2
Do you know how to solve this problem?

Thanks

Hi @adc-zhao, these containers are setup for building ROS2 from source, so you would instead use rosinstall_generator to clone and then build the nav2 nodes. Or at that point you might just want to have installed Humble from the get-go from apt instead of source, or use the Isaac ROS debian server: https://nvidia-isaac-ros.github.io/getting_started/isaac_ros_buildfarm_cdn.html
