wget 无法正常工作：没有到主机的路由

我正在使用 Ubuntu 20.04。每次使用时wget都会出现

failed: No route to host

适用于每个网站。这里可能存在什么问题？

I found out my problem virtualbox is only connecting to google services.

答案1

ping仅接受主机名。来自URL - 维基百科：

典型的 URL 可以采用以下形式http://www.example.com/index.html，表示协议 ( http)、主机名( www.example.com) 以及文件名 ( index.html)。

另外，来自语法 - 主机名 - 维基百科：

主机名由一系列标签用点连接。例如，“en.wikipedia.org”是主机名。每个标签的长度必须为 1 到 63 个字符。整个主机名（包括分隔点）最多包含 253 个 ASCII 字符。

显然，https://dl.winehq.org/wine-builds/winehq.key是 URL，而google.com是主机名。这就是为什么在您的情况下，ping后者可以完美地工作。
