The following signatures were invalid for raring security

By Shady Atef

I got this famous error and I really can’t solve it:

    E: GPG error: raring-security Release: The following signatures were invalid: NODATA 1 NODATA 2

What I have Tried till now

     sudo rm /var/lib/apt/lists/* -vf
     sudo apt-get update
Then I tried
sudo apt-key adv --recv-keys --keyserver 40976EAF437D05B5
sudo apt-key adv --recv-keys --keyserver 3B4FE6ACC0B21F32

PS: I know this may be duplicated but All Solutions and web surfing didn’t work with me
I work on Linux Mint 15 64bit
