Question

从WSL升级到WSL2之后

sudo apt-get update

之后不再有效>>

wsl --set-version Ubuntu-18.04 2

输出：

> sudo apt-get update

回到WSL1之后，问题再次消失。在Debian上也一样，在CentOS中也类似..因此WSL2必须有一个错误。

Windows10的内部版本是19041，今天已安装。

WSL2的解决方案了吗？问候

从WSL升级到WSL2后，在wsl --set-version Ubuntu-18.04 2之后sudo apt-get update不再起作用输出：> sudo apt-get update错误：1 http://security.ubuntu.com/ubuntu ...
