I think you have been around the forumns long enough to know not to do this. Post the code, using code tags, from your local project. How do we know what you may have changed, or perhaps something didn't import. We can't tell that from the link you posted.

 

I haven't actually wrote any code yet. I haven't got that far into the project

 

I've just restarted the project, imported the Asset package and got the following error, using last year's version of Unity on Ubuntu Linux, a supported OS, WTF?!

 

So I've just updated Unity to last year's latest version, and got the following error on the 3D Platformer project, from Coursera.

 

I officially give up! I Tweeted the course tutor, he's never gonna respond.
