ubuntu - Windows10 WSL2 Ubuntu/Debian # 无网络

Question

从 WSL 升级到 WSL2 后

sudo apt-get update

不再工作。后: wsl --set-version Ubuntu-18.04 2输出是:

> sudo apt-get update
Err:1 http://security.ubuntu.com/ubuntu bionic-security InRelease
  Temporary failure resolving 'security.ubuntu.com'
Err:2 http://archive.ubuntu.com/ubuntu bionic InRelease

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

回到 WSL1 后，问题再次消失。在 Debian 上也是如此，在 CentOS 上也是如此。所以 WSL2 一定有一个错误。
Windows10 build 版本为 19041，今天安装。
WSL2 的任何解决方法？
问候

Answer 1

生成的文件/etc/resolv.conf 是:

nameserver 172.24.0.1

..必须将其更改为

nameserver 8.8.8.8

这解决了问题
