In Exercise 9.13, the prompt recommends using the shell command:
find /opt/ros/kinetic/ -name Test.action
This returns an error:
find /opt/ros/kinetic/ -name Test.action
find: '/opt/ros/kinetic/': No such file or directory
However, I found a solution by changing “kinetic” to “noetic”.
Solution:
find /opt/ros/noetic/ -name Test.action
I believe this is correct since the course is based in noetic. If an admin could make this change, it may reduce future confusion for students.
