如何通过 Ubuntu 17.10 中的默认存储库安装 Virtual Box 的扩展包？

Question

Virtual Box 已通过以下方式安装：

sudo apt install virtualbox

然后我继续安装扩展包：

sudo apt install virtualbox-ext-pack

这遇到了错误：

sudo apt install virtualbox-ext-pack

我已经尝试使用“apt purge ...”重新启动并重新安装。尽管如此，问题仍然存在。

如何通过 Ubuntu 17.10 中的默认存储库安装 Virtual Box 的扩展包？

我只是注意到目录/usr/share/virtualbox-ext-pack是空的。在参考系统上，该文件夹包含该*.vbox-extpack文件。也许这是这里的代理问题？

Answer 1

当您运行此命令时：

sudo apt install virtualbox-ext-pack

在安装过程中，使用工具virtualbox-ext-pack从http://download.virtualbox.org/下载wget。

但是正如您所说，您使用代理，apt并且您也无法访问http://download.virtualbox.org/站点，没有代理（因为curl: (6) Could not resolve host: download.virtualbox.org输出，在您的评论中）。

因此，您应该使用以下命令在终端上设置代理（不仅仅是 apt）：

export http_proxy='http://proxyserveraddress:port'    
export https_proxy='https://proxyserveraddress:port'

在终端设置代理后，你的问题应该解决了。
