How do I install gtk-v4l on Ubuntu 16.10?

By Slava Fomin II

I’m running latest Ubuntu 16.10 desktop operating system.

How do I install gtk-v4l package to control my webcam settings?

I’m getting the following errors during apt-get update:

W: The repository ' yakkety 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  404  Not Found

I was following this guide: Webcam settings control on Ubuntu Linux operating system.
