我把CDN改成本地的http://mirror.kakao.com，出现如下错误。

我该如何解决？

Answer 1

我找到了。这是因为 Avast 防火墙。当我禁用它时它工作得很好。

Answer 2

作为@Seokmin Hong said

我找到了。这是因为 Avast 防火墙。当我禁用它时它工作得很好。

当当前连接设置为“公共网络”时，它特别不起作用。 当它更改为“私人网络”时，它会自动工作。 无需禁用防火墙，只需将其设置为私有即可。

Answer 3

这是从 WSL2 使用 Ubuntu 时的解决方案

Answer 4

使用WSL2 时，您需要修复防火墙。这在使用 docker 时最需要。

对于其他任务，例如使用 python pip install，没有问题。

您可以切换回wsl1（降级），它可以完美运行。

Answer 5

我已经通过将开发者模式设置为开启解决了这个问题

Answer 6

我在 WSL2 上遇到了与 ubuntu 20 类似的问题。我尝试将图像切换到 wsl1，但有趣的是它不起作用。在我的情况下，它原来是一个代理问题。原来 apt-get 不使用环境变量中的代理，必须在 /etc/apt/apt.conf.d/proxy.conf 中专门设置

Answer 7

我也有同样的问题，也是 Avast。在防火墙中将我的网络从公共网络更改为私人网络已为我解决了问题。
