So, having made the mistakes with my previous virtual instance of Kali Linux, I’ve begun to start over with a new copy. When I first got mine, I remember not knowing what to do with it, and I stumbled upon the Offensive Security sources.list help page and figured it out.
The sources.list file can be found in /etc/apt/sources.list
I am comfortable with Vi, so i typed: vi /etc/apt/sources.list
This spits out the content of your particular file, which should look a lot like mine two commented out lines than:
deb http://http.kali.org/kali kali-rolling main non-free contrib
# deb-src http://http.kali.org/kali kali-rolling main non-free contrib
If you are not familiar with vi or vim, you have to type insert to change the data in a file. all I did to this file was delete the # in front of deb.src
to exit insert mode, press the esc key
next, type colon, :
then to save the changes, type wq! and press enter.
Finally, type apt-get update && apt-get upgade
and sit back and watch it install.
