```
Here are the manual steps to install VirtualBox Guest Additions kernel modules inside the VM:

    Download the ISO file, e.g.

    wget http://download.virtualbox.org/virtualbox/5.0.20/VBoxGuestAdditions_5.0.20.iso -P /tmp

    Mount the ISO file:

    sudo mount -o loop /tmp/VBoxGuestAdditions_5.0.20.iso /mnt

    Run installer (add -x after sh to debug):

    sudo sh /mnt/VBoxLinuxAdditions.run

To find the right version of ISO file, check it at: http://download.virtualbox.org/virtualbox/

If you're using Vagrant, installation is much simpler by following these commands:

vagrant plugin install vagrant-vbguest
vagrant up
vagrant vbguest
```

2. Desktop environment: `sudo aptitude install kubuntu-desktop`
