This happened to me in a recent install, too, but I had installed the Google repository - I see that you have installed it, as well, in your first line...

Navigated to /etc/apt/sources.list.d/.

Edited google.list by invoking sudo nano google.list.

Commented out the source with a #

Saved and ran sudo apt-get update

In case you like to do it in the terminal:

sudo nano /etc/apt/sources.list.d/google.list

#deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

Save and Close the file using Ctrl+X and then Y, and try updating using:

sudo apt-get update

Error solved!

I had the same kind of problem. I go in /etc/sources.list then I open the files concerned by the error.

I saw that a line was repeated and I just removed one of the duplicated lines.

Now I don't have the error anymore.
