why is my kali trying to get ununtu updates?

my sources.list file reads as follows:

GNU nano 5.4 /etc/apt/sources.list
# See https://www.kali.org/docs/general-us...-repositories/
deb http://http.kali.org/kali kali-rolling main contrib non-free
deb http://http.kali.org/kali kali-last-snapshot main non-free contrib
deb http://http.kali.org/kali kali-experimental main non-free contrib

# Additional line for source packages
# deb-src http://http.kali.org/kali kali-rolling main contrib non-free
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


there's a bunch of lines after this telling me why it can't do what it cant do from where it cant do it from blah blah.

but so, my question here is, what happened? why is it trying to grab stuff from repositories that aren't listed in the sources.list file? and how do i stop it from doing this?

im trying to get my TP-Link usb wifi adapter to run, and i need to update the headers, actually add repositories so that i can get the updates and upgrades i need to finish the driver patching.

any help you guys and gals could offer would be much appreciated.
