No packages installed in ros/fuerte

edit

I am completely new to ROS and am just trying to get up and running.

I am on a Mac computer running a VirtualBox VM with Ubuntu 16.04.

I followed the instructions to install ROS and everything went fine.

Then, I moved on to the tutorial, and everything went fine until I tried to create a new workspace.

When I ran the command rosws init ~/fuerte_workspace /opt/ros/fuerte I got the error message

Using ROS_ROOT: /opt/ros/fuerte

ERROR in config: Is not a local file, nor a valid URL [/opt/ros/fuerte] : unknown url type: /opt/ros/fuerte

I just checked the folder /opt/ros/ and the only folder in it is kinetic. There is no fuerte folder in /opt/ros/.

What can I do to solve this issue?

EDIT:

I discovered why I was confused.

I was using the new "Reader View" mode on Firefox, which displays both versions of creating a workspace without differentiating between the two.

Tip to self: Don't use "Reader View" when trying to follow important instructions.

(I'm new to Firefox, so I had no idea it would change how the page looked that much.)
