OpenCV nonfree-repository

[imprs]

Hello,
I am unable to install openCV-nonfree repository on ubuntu precise (12.04). While running sudo apt-get upadte I am getting this, I have attached a screenshot here.

When I have worked on the issue, I found this:

and further..

So, now my question is : openCV nonfree-repository is available only for "trusty" and no-more available for precise or I am getting it wrong!

Sorry if it looks like silly but I'm not getting any solution for it :)

Thanks in advance :)

I have the same problem here on 12.04

Being unable to install the examples is making it impossible to follow the book.
