Hello, I'm using ROS melodic on Ubuntu and following tutorial 5 on wiki.ros.org, and I am meant to be running turtlesim, but I am getting this message:

[rospack] Error: package 'turtlesim' not found

I am not getting results on google when searching for this error and to my understanding I thought turtlesim already came installed with ros. I am new to ROS so can anyone tell me why this error is happening?

Did you install ROS via apt?
