Important!!!

Type of bug

Issue Description

Hello, I have problems with chapter 2 " ros2 launch br2_tiago sim.launch.py".

I get the following error messages:

play_motion2_node-10] [ERROR] [1683104855.352795642] [play_motion2]: Service /controller_manager/list_controllers not available. [play_motion2_node-10] [ERROR] [1683104855.352955540] [play_motion2]: There are no active JointTrajectory controllers available [tuck_arm.py-15] [ERROR] [1683104855.369452866] [arm_tucker]: play_motion2 is not ready

I have the following packages installed (and more ;-) ) : controller_manager controller_manager_msgs play_motion2 play_motion2_msgs

I followed the installation guidelines in the presentation.

What has gone wrong?

Thanks, Verena

Hello @VerenaSchmidt11 ,

please try again to launch everything after updating your pc. To do this, run the following commands:

sudo apt update
sudo apt upgrade

If by any chance it still doesn't work, repeat the steps again to create the workspace.

We are waiting for your answer.

^^

Thanks. I found out that most of the problems were a result of using a VM and Oracle VM VirtualBox. Since changing to a VM in the cloud it works.

Perfect. Closing...
