“Ok, for this exercise you’ll need a copy of Ubuntu
Linux already installed on your PC. I chose Ubuntu because it’s one
of the friendliest Linux distributi ons available, as you will see
in a moment.“Before installing VirtualBox, you’ll need to install two
additional packages on your Ubuntu system. Open a terminal window
(Applications | Accessories | Terminal), and type sudo apt-get
update, followed by Enter. If Ubuntu asks for your administrative
password, type it, and hit Enter to continue.“Once the package list is updated, type sudo apt-get install
dkms, and hit Enter; then type Y and hit Enter to install the DKMS
package.“The other package needed before you can install VirtualBox is
build-essential. This package contains all the compiling tools
VirtualBox needs to build the kernel module. Type sudo apt-get
install build-essential, and hit Enter. Then type Y, and hit Enter
again to conti nue. Wait for the $ prompt to show up again, type
exit, and hit Enter to close the terminal window. Now you can
proceed to install VirtualBox.”
