sudo apt-get install virtualbox-guest-additions-iso It is not recommended to install these in newer releases of Virtual Box as obtained from the Oracle repository (see below).Īlternatively we can install the package virtualbox-guest-additions-iso in the host Ubuntu. This will install guest additions matching the Virtual Box version as obtained from the repositories.

In case we have installed the OSE edition of Virtual Box from the repositories we can add the guest additions from the repositories in the guest. Installing Guest additions from the repositories VirtualBox was NOT able to really mount the GuestAdditions.iso image automatically via the 'Device -> Insert GuestAdditions CD Image.'.įinally I got it mounted! Then just go into the mounted dir ( cd cdrom) and exec the installer with sh n (remember you are root).If you have trouble installing Ubuntu in a VirtualBox VM, because the installer window does not fit the low resolution screen size, you can move the window with Alt+ F7.

I tried all the solution on the net and couldn't make it work via GUI (like all the other answers). Every reload was always finding the old one (5.1 installed on VirtualBox 5.1). And now I get reported (by vbguest plugin ) that I need an updated version of GuestAdditions. In my case I updated my macOS, I was forced to upgrade Virtualbox to 5.2 (I installed without uninstalling first). Keep in mind that you not only have to insert the virtual cd, but actually run the installer before the vboxfs filesystem type will work.Īll the answer say to go via GUI and 'Leave emtpy' the CD drive, but that wasn't working for me: still VERR_PDM_MEDIA_LOCKED error. Hitting the 'Force Unmount' button would be another way to unmount your drive, and after doing that the insert guest additions cd menu option should work the second time you use it. The linked article provides instructions for doing this. Googling for that produces the answer in the first result: Įssentially, you need to unmount your virtual cd drive before inserting the guest additions cd image. Guest additions should include the software you need to use the vboxfs filesystem type.ĮDIT: Based on your updated question, the real cause error you are seeing is VERR_PDM_MEDIA_LOCKED. Run the appropriate setup program from the virtual CD drive. When you choose it, it will be as if you inserted an installation CD to your virtual machine. Insert Guest Additions CD Image is the same thing as Install Guest Additions in a different version of Virtual Box.
