我在Win10(2004) 系统上安装linux kali子系统,一直出现Failed to fetch...错误，希望得到帮助

下面是详情

└─# sudo apt-get update && sudo apt-get upgrade

我在网上看到一些解决方案，一般都是更改源和代理这些我都做了,但是并不能解决问题,当然DNS和源我也都尝试了其他的，现在的如下

--- /etc/resolv.conf
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /># [network]
# generateResolvConf = false
nameserver 114.114.114.114
nameserver 223.5.5.5
nameserver 223.6.6.6
--- /etc/apt/sources.list:
deb https://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib
deb-src https://mirrors.ustc.edu.cn/kali kali-rolling main non-free contrib

应该确定的是我的网络没有问题(我相信这是一种检验方式)

└─# ping 114.114.114.114

我还看到d一些提到代理的问题，我安装了软件但我并未运行，我也根据提示输入了一些cmd命令，同样无果

我这么做的目的是正常安装更新软件，比如安装桌面环境等
事实上会出现下面这样

┌──(root💀Laptop)-[***]
