我正在尝试在办公室笔记本电脑上使用 WSL2 运行 Ubuntu。
问题：
当我尝试运行 apt-get update 或任何安装命令时，例如：apt-get install gcc，它总是以101: Network is unreachable.
我迄今为止尝试过的解决方案：
防火墙
我最初的猜测是办公室防火墙可能阻止了连接，但快速 ping 检查后我发现它运行正常。此外，我还在 Chrome 中浏览了 URL，它没有任何问题。
$ ping 91.189.91.39 PING 91.189.91.39 (91.189.91.39) 56(84) bytes of data. 64 bytes from 91.189.91.39: icmp_seq=1 ttl=51 time=256 ms 64 bytes from 91.189.91.39: icmp_seq=2 ttl=51 time=256 ms ^C --- 91.189.91.39 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1002ms rtt min/avg/max/mdev = 255.540/255.757/255.975/0.217 ms解析器配置文件问题。
我尝试将默认名称服务器更改为 8.8.8.8 并尝试使用其他 DNS 提供商，但问题并未得到解决。此外，由于 ping 可以正常工作，因此 DNS 解析器应该没有问题。
现在我能够找到更多的解决方案，例如强制 apt 使用 IPv4、删除虚拟机管理程序交换适配器和其他类似的解决方案，但它们的问题似乎与我所面临的问题无关，而且我不想继续在黑暗中射箭。
任何帮助或指引都将不胜感激。谢谢
