我正在尝试使用 Ubuntu 的 WSL2 安装。
apt-get不起作用。例如，如果我想安装，net-tools我会得到
daniele@IOS-PC:~$ sudo apt-get install net-tools

奇怪的是，我能够 ping 通服务器的 IP 地址和名称：

如何apt-get正确使用该命令？
答案1
最近，我遇到了类似的问题，我无法使用新的 Docker Desktop（基于 WSL 2）提取 Docker 映像。其他人也遇到过这种情况，并发现了以下问题：AVM FritzBox 路由器的硬件加速防火墙存在一个错误。
唯一的“解决方案”（实际上是变通方法）是关闭防火墙加速器。为此，请转到http://fritz.box/support.lua（或http://192.168.178.1/support.lua或其他）并登录。在此页面上的某个地方，您会找到一个用于控制防火墙硬件加速的复选框。在德语中，它看起来像这样：
只需禁用它并再试一次。
但请注意：这将严重限制 FritzBox 的路由性能。如果您订阅了快速互联网，您会感觉到这一点。
