How to install Virtual Box's Extension Pack via default repository in Ubuntu 17.10?

  • 772

Virtual Box had been already installed by:

sudo apt install virtualbox

Then I went on installing the extension pack:

sudo apt install virtualbox-ext-pack

This runs into the error:

sudo apt install virtualbox-ext-pack

How to install Virtual Box's Extension Pack via default repository in Ubuntu 17.10?

I just noticed that the directory /usr/share/virtualbox-ext-pack is empty. On a reference system the folder contains the *.vbox-extpack file. Maybe this is a proxy problem here?

virtualbox apt 17.10

    When you run this command :

    sudo apt install virtualbox-ext-pack

    During installation , the virtualbox-ext-pack is downloaded from http://download.virtualbox.org/ with wget tools.

    But as you said, you use proxy for apt and also you can't access the http://download.virtualbox.org/ site, without proxy (because of curl: (6) Could not resolve host: download.virtualbox.org output, in your comments).

    So you should set a proxy on your terminal (not just for apt) with this commands:

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

    After set proxy in terminal, your problem should be solved.
