I've been following a tutorial from another website to set up Kali Linux on my RPi3. After booting for the first time, I open the terminal to install GParted and receive errors after entering apt-get install gparted. I'm using RPi3 ver. 2017.3.

The error messages I'm receiving are as follows:

Err:1 http://http.kali.org/kali kali-rolling/main armhf libgtkmm-2.4-1v5 armhf 1:2.24.5-1
404 Not Found
Err:2 http://http.kali.org/kali kali-rolling/main armhf gparted armhf 0.25.0-1+b1
404 Not Found
E: Failed to fetch http://http.kali.org/kali/pool/main/....5-1_armhf.deb 404 Not Found
E: Failed to fetch http://http.kali.org/kali/pool/main/...1+b1_armhf.deb 404 Not Found
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?

I've been getting similar 404 issues while attempting other installations and updates but this is the first one I've encountered. I've tried flashing the image to different SD cards and attempting to install and update afterwards and nothing has worked yet.
