为什么无法 apt 解析名称？

喜欢还有很多其他问题，我不能跑apt-get update 有时。重新启动或等待一段时间即可解决问题。我从未遇到过 ping 或访问浏览器中相应 URL 的问题。

我尝试了所有获得支持的答案，但都无济于事。apt这与我的浏览器有什么不同ping？例如，当我运行时，apt-get update我看到的是：

在我的浏览器中访问该页面时一切正常。我怎样才能让apt-get“正常工作”？

以下是我的内容/etc/apt/resolv.conf：

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 127.0.1.1
search home.gateway

答案1

从终端运行此命令，以后您就可以正常apt使用:)apt-get

echo 'Acquire::ForceIPv4 "true";' | sudo tee /etc/apt/apt.conf.d/99force-ipv4

答案2

如果/etc/atp/apt.conf存在，请复制该文件，然后编辑原始文件以注释掉以下行（如果不在代理服务器后面）：

Acquire::http::Proxy "http://proxyaddress:proxyport";
