The Oracle VM VirtualBox® User Manual states that VirtualBox is installed into /opt/VirtualBox/, but it is not at that location. I tried

$ cd /
$ sudo ls -lR | grep "VirtualBox"

and also searched for vbox without any luck on either. A search on AskUbuntu just returned a heap of hits on folders shared between the guest and host.

Really, I am just after the Windows 7 guest additions .iso file as you can't download it separately from the Oracle site anymore. Also, how do you install the extensions?

    The guest additions iso is in /usr/share/virtualbox/VBoxGuestAdditions.iso(if you installed the virtualbox-guest-additions-iso package). –  Oct 23 '14 at 10:40

The guest additions iso is in /usr/share/virtualbox/VBoxGuestAdditions.iso (if you installed the virtualbox-guest-additions-iso package).

How do I know this?

This command:

dpkg -L virtualbox-guest-additions-iso

lists all the files that the virtualbox-guest-additions-iso package installs and where they are located. You can do this for any package you have installed.

You can also use the Synaptic Package Manager to get this information graphically.

To install the guest additions:

Just boot the virtual machine, and when it gets to the desktop open the Devices menu, click Install Guest Additions CD Image... and follow the instructions.

  • So far for VirtualBox 6.1.40 the directory is still the same - /usr/share/virtualbox/ - it even if was installed through sudo dpkg -i XXX.deb – Manuel Jordan Dec 08 '22 at 21:27
  • VirtualBox always failed to download Guest Additions and it turns out I just needed to install this (virtualbox-guest-additions-iso) package. – Octopus Dec 28 '23 at 10:44

SOLVED: You can get the VboxGuestAdditions_?.?.?.iso from http://downloads.virtualbox.org/virtualbox/
