I'm installing ROS2 Foxy, and when a run the command:

How did you install python3.8? I think you don't use apt.
Also, it is recommended to attach the error as text, not as an image.

Did you download from apt on ros2?
what happen after you type this in terminal
/source /opt/ros/foxy/setup.bash?also whats the output of
python3 --version?Asked by kak13 on 2021-08-25 20:15:36 UTC
When I update the Ubuntu 18 to Ubuntu 20, the python3 it was install.
source /opt/ros/foxy/setup.bash=>bash: /opt/ros/foxy/setup.bash: No such file or directorypython3 --version=>Python 3.8.10Asked by Jose-Araujo on 2021-08-25 21:45:58 UTC
bash: /opt/ros/foxy/setup.bash: No such file or directoryTHis means you don't have foxy installed. Try re-install foxy

@Jose-Araujo: could you clarify why you want to build Foxy from source? There isn't really any immediate need when you are running Ubuntu
20.04. Or is this nonamd64?@kak13:
I'm sort-of assuming @Jose-Araujo knows that. His build is failing, that would seem to be the main problem here.
Additionally, the default
installlocation for a from-source build would be$colcon_ws/install, not/opt/ros.Asked by gvdhoorn on 2021-08-26 01:44:31 UTC
I must be confused with colcon build then.
I assume that colcon build relies on /opt/ros/foxy/setup.bash to continue the colcon build.
My bad, Jose haha

@gvdhoom : so I follow this instructions https://docs.ros.org/en/foxy/Installation/Ubuntu-Development-Setup.html. The recommended it's that https://docs.ros.org/en/foxy/Installation/Ubuntu-Install-Binary.html?
Asked by Jose-Araujo on 2021-08-26 14:52:38 UTC
Well, what is your purpose?
You could have a good reason for wanting to compile everything from sources, but if you can't think of any, you'd probably be better of with an installation using
apt. So that would indeed be the second link you shared.Asked by gvdhoorn on 2021-08-27 01:40:48 UTC
