Unable to locate package ros-indigo-rosserial-arduino
I keep on getting, "Unable to locate package ros-indigo-rosserial-arduino" in the terminal. I even replaced indigo in that line of code with my current version of ROS, Melodic, and it still didn't work. Does anyone have a solution to this? I installed ROS correctly, I think. Does anyone know what to do?
I am doing a research project using ROS and an arduino uno and need to be able to install rosserial in order to connect the two and begin what I was doing. If anyone has a quick solution/workaround, it would be much appreciated.
Just some extra information to help diagnose the issue: I am running Ubuntu Linux 18.04 on an Oracle Virtual Machine. Also, as stated above, I installed the most recent version of ROS, that being Melodic.
Thanks!
