  • 系统：Windows 10 PRO 19044.1415

  • WSL 2，Ubuntu 20.04

ping到 google.com 也失败了：ping: google.com: Temporary failure in name resolution

已经完成了：

  • wsl.conf其中包含以下几行：
[network]
generateResolvConf = false
  • resolv.conf用几个重新创建nameserver：
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 1.1.1.1

尝试过：

  • 添加nameserver 8.8.8.8到wsl.conf。不起作用。
  • 保持单行nameserver在内resolv.conf
  • 关注这些步骤
  • New-NetFirewallRule -DisplayName "WSL" -Direction Inbound -InterfaceAlias "vEthernet (WSL)" -Action Allow从这里

答案1

终于找到答案了。这甚至不是我的错...

这个建议帮了我大忙，sudo apt update终于成功了。如果你没有.wslconfig文件，就自己创建吧。

最终得到这个内部内容resolv.conf：

nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 1.1.1.1
nameserver 208.67.222.222  # OpenDNS address
nameserver 192.168.0.10  # ipv4 address of your windows machine. *1

我发现这与我的情况相关：

我不得不关闭 Symantec Network Threat Protection
