I have been using Ubuntu 16.04 for the last few years. Every time I run an update before installing any new software. But since yesterday whenever I run update it prints in the terminal below: 

Hit:1 http://de.archive.ubuntu.com/ubuntu xenial InRelease          
Ign:4 http://dl.google.com/linux/chrome/deb stable InRelease                   
Err:12 http://dl.google.com/linux/deb testing/non-free amd64 Packages
  404  Not Found [IP: 172.217.18.14 80]
Reading package lists... Done
W: The repository 'http://dl.google.com/linux/deb testing Release' does not have a Release file.
N: Data from such a repository can't be authenticated and is therefore potentially dangerous to use.
N: See apt-secure(8) manpage for repository creation and user configuration details.
E: Failed to fetch http://dl.google.com/linux/deb/dists/testing/non-free/binary-amd64/Packages  404  Not Found [IP: 172.217.18.14 80]
E: Some index files failed to download. They have been ignored, or old ones used instead.

Does anyone know how-how to fix these issues?

Open System Settings -> Software & Updates -> Other Software

and remove that http://dl.google.com/linux/deb/dists/testing/non-free/binary-amd64/Packages repository from software sources.

You have wrong lines in /etc/apt/sources.list (or in some *.list file inside /etc/apt/sources.list.d/).

For Google Chrome it should be:

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

For Google Earth:

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

Remove the problematic line http://dl.google.com/linux/deb testing or change to one of the above by hand or with Software & Updates (software-properties-gtk) on Other Software tab.
