nav2 simulation example doesn't work

[david-wb]

When I try to launch the gazebo + nav2 simulation, it throws an exception: package 'pal_nav2_bringup' not found

Full output:

:~/pmb2_public_ws$ ros2 launch pmb2_gazebo pmb2_gazebo.launch.py is_public_sim:=true navigation:=true

How can I install the missing package? Thanks for your help.

I encountered the same situation, how did you solve it. Thank you for your guidance

@MrVBian Yes, I had to manually download pmb2_navigation package to the src folder of the workspace and rebuild, but then I ran into other problems. It seems this repo is severely outdated.

@david-wb Thank you for your reply. I solved this problem and shared it with you.
I updated the tiago_navigation repositories like you. But I seem to have a step more than you, and execute the vcs pull instructions in the roots of the project. Hope to help you.
If my answer can't help you. At least for me, the project can be running, I suggest you open the problem.I made a docker container, if you need to contact me.
