Hi The Construct Team,
I am on the ROS2 Basics in 5 Days Galactic (C++) course and I am getting this error:
user:~$ source /opt/ros/galactic/setup.bash user:~$ ros2 run tf2_tools view_frames.py No executable found user:~$
I tried to do
sudo apt install ros-galactic-tf2-tools but that fails.
Output of sudo apt install
