Answer 1

What you are seeing is just a warning and not an error. The update is still happening.

If you want to upgrade, you'll have to use sudo apt-get upgrade or sudo apt-get install --only-upgrade <packagename>

Answer 2

Kali users should have these entries in their /etc/apt/sources.list file:

Enter web site: enter link description here Now copy The Kali Rolling Repository

deb http://http.kali.org/kali kali-rolling main contrib non-free

deb http://old.kali.org/kali sana main non-free contrib

deb http://old.kali.org/kali moto main non-free contrib

Terminal:

apt-get update

apt-get upgrade
