I am trying to install Win-Kex and I am having a heck of a hard time getting it to install.

I have a Lenovo T520 laptop running: Windows 10 Pro version 2004 OS build 19041.450

C:\WINDOWS\system32>wsl --list --verbose
NAME STATE VERSION
* kali-linux Running 2

I have everything setup correctly with version 2 of wsl

akore@LenovoT520:/mnt/c/WINDOWS/system32$ sudo apt update && sudo apt install -y kali-win-kex
Err:1 http://http.kali.org/kali kali-rolling InRelease

W: Some index files failed to download. They have been ignored, or old ones used instead.

This seems to be where the main problem is. Anyone know how to get this to actually install?
