Greetings,
I have kali linux 2016
Immediatly after i installed the OS i use the terminal to update it and upgrade it.
It didnt work, so i checked my sources list and it was blank. So i added the following repository
deb http://http.kali.org/kali kali-rolling main contrib non-free
Tried to update and upgrade, it did'nt work.
The terminal said a bunch of "Failed to fetch" and 404 not found.

What should a do next?

Please and Thank You
