通过路由追踪测试后发现，连接 mirrors.dgut.edu.cn 是通过我校 CERNET 网络，并非中国电信。 正确的 IP 应当为 42.247.46.244。

Is the problem only found in ubuntu-releases? Or you also met this problem with other repo.

同样出现在其他源，例如 CentOS，另外我不认为需要使用英语来交流。

目前来看，从电信过去是没啥问题的，教育网暂时还没环境测试。 image

更新: 找朋友（广东联通）测试了一下，windows 下的 curl 复现出来了，wsl1 下的 curl 也不正常，使用 wsl2 则正常，都测试过最新版本。 wsl2 正常的 curl 版本信息 image

最后在 windows powershell 下使用 wget 正常。 image

@lyekumchew 跟工具没什么关系，我是昨天在宿舍（电信）使用 Chrome 下载的时候，一直遇到“网络错误”，然后下载中断，前天在梅州（电信）也下载过，均是如此。
