Windows PS 和 WSL2 似乎无法发送 icmp echo 请求或下载任何内容

我更新到Microsoft Windows [版本 10.0.19041.264]（新的 2004 年 5 月更新）以便检查 wsl2 并查看所有新功能。我已经设置好 wsl1 并开始运行，因为我经常喜欢用它来进行 IRC。更新之前一切都运行良好。

因此我更新到了 2004，并按照 wsl2 的安装步骤进行操作（https://docs.microsoft.com/en-us/windows/wsl/install-win10），一切进展顺利。没有发生任何错误。

然后我尝试了一下sudo apt update && sudo apt full-upgrade，结果如下：

好吧……所以有问题。所以一定是无线问题，对吧？我做了lshw -C network

*-network:0

       logical name: eth0
       serial: 00:15:5d:f3:23:81

所以它看起来好像看到了我的无线网卡...所以接下来我尝试了一下，ping结果得到的是Temporary failure in name resolution

我按照这里的解决方案：https://www.digitalocean.com/community/questions/how-to-resolve-temporary-failure-in-name-resolution-issue

但只有当你将以下内容写入时它才有效/etc/wsl.conf

[network]
generateResolvConf = false

因此请确保sudo nano /etc/wsl.conf将其粘贴到那里，CTRL+O 和 CTRL+X，然后退出并进入 powershell wsl --shutdown，然后重新启动它。这为我解决了这个问题。

让这成为其他遇到此问题的人的文档。
