When I installed Orace Virtual Box I installed guest additions as the secondary master drive.

The location of the guest additions is

C:/prog files/oracle v box/guestaddition.iso

I know I did not know why I installed this on the original Oracle Virtual Box install and now I am unable to successfully install Guest Additions through the command line on my Ubuntu installation.

I was able to successfully download the guest additions iso through ubuntu however I have an error log message when trying to install it.

Is there any specific error message I need to provide to get to the core of this problem?

I could post the entire error log of the unsuccessful guest additions install from terminal however it is quite lengthy.

I'm thinking that there is a conflict between the already installed Oracle guest additions and the successfully downloaded ubuntu but not installed guest additions.

Thank you.


When I select Devices > Install Guest Additions

it returns

"unable to mount CD/DVD image C:/prog files/oracle v box/guestaddition.iso on the machine MyUbuntu. Would you like to force mounting of this medium?"

Could not mount he media/drive C:/prog files/oracle v box/guestaddition. VERR_PDM_MEDIA_LOCKED
