Question

报错信息的一个截图

我之前设置的dns 解析到8.8.8.8（主） 和 223.5.5.5 尝试几次修改之后 都不行 不知道要怎么办了？

解决问题的时候发现：选择最佳服务器 未找到服务器错误

觉得两者有什么联系

真心求助啊

Answer 1

The Alibaba Cloud DNS you are using may not be able to connect in your network environment. To be honest, Alibaba Cloud DNS rarely works properly here.
Changing the DNS will solve the problem.

Answer 2

dns error, restore to default

Answer 3

1. Don’t set the DNS randomly, just use the DNS provided by your own network
2. Launchpad mainly contains some compiled third-party packages. It is indeed "easy" to connect to this server in China.
