This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • This is a Windows related question since you need to install them in the host. So seems off topic to me. And ... virtualbox.org/manual/ch04.html#idp53491632 – Rinzwind Dec 27 '14 at 14:10
  • Why -1 for this question ?? Means if anybody is asking the question just give the right answer man !! anyways i got the link – gurupal singh Dec 27 '14 at 14:12
  • Dunno. Maybe cuz you should ask this on a windows platform? – Rinzwind Dec 27 '14 at 14:19
  • @Rinzwind why on windows platform. I have no issues with host machine. I'm getting problems with virtual box that contains Ubuntu 12.04 server as guest machine . – gurupal singh Dec 27 '14 at 15:05
  • @Rinzwind I tried the answer from the link given by you. The answer told me to first install dkms for building external kernel modules but whenever i tried to install dkms it shows the unmet dependencies issue (dkms depends on gcc) & even i tried to install gcc , but again i got the issue E: Package 'gcc' has no installation candidate ..!! – gurupal singh Dec 27 '14 at 15:12

If you already downloaded a VBoxGuestAdditions.iso file to your host filesystem, you should be able to install the image from the VM's Devices menu using Insert Guest Additions CD Image...

Note that does not actually install the guest addition components, it just makes the ISO available as a virtual CD. On Ubuntu Server guest OSes, it does not even mount the virtual CD within the guest system.

Alternatively, you can download the ISO straight into the guest system from the repository, using

sudo apt-get update
sudo apt-get install virtualbox-guest-additions-iso

Once you have made the ISO available by one of the above methods, you must mount it somewhere in the filesystem. I am going to assume you want to use mountpoint /mnt for that, but you can create a different mountpoint if you wish.

If you inserted the ISO image as a virtual CD:

sudo mount /dev/cdrom /mnt

If you installed the guest additions ISO package from inside Ubuntu:

sudo mount /usr/share/virtualbox/VBoxGuestAdditions.iso /mnt

Finally, navigate to the mount point and run the installer:

cd /mnt

sudo ./VBoxLinuxAdditions.run
  • hi, thanks for the answer but i insert the VirtualBox Guest addition(which is located in C:\Program Files\Oracle\VirtualBox of my host machine windows 7)from the devices menu in Virtual Box but i can't see the ISO file in - media/cdrom !! – gurupal singh Dec 27 '14 at 15:34
  • @gurupalsingh on server systems you won't see it in /media/cdrom unless you manually create that mountpoint and mount it there. If you tried to do that and it failed, then please post any error messages. – steeldriver Dec 27 '14 at 15:39
  • thank man , that worked but with errors ..!! – gurupal singh Dec 27 '14 at 15:46
  • I got this error - "The gcc utility was not found.If the following module compilation fails then this could be the reason & u shud try installing it.Building the main guest additions module..fail !! (Look at /var/log/vboxadd-install.log to find what went wrong) could not find the X.org or XFree86 Window System, skipping. " – gurupal singh Dec 27 '14 at 16:00
