[Virtualbox Guest Additions] "Please install the build and header files headers? - Debian

Install the following on your Ubuntu Guest :

sudo aptitude install build-essential linux-headers-`uname -r`

The re-try the Additions, you should be fine :)

Install Guest Additions on Linux guest

Again, a fairly simple procedure. Repeat the first step. This will mount the VirtualBox Guest Additions ISO (included with the program) as a CD-ROM drive inside the virtual machine.
A file manager windows might popup, depending on your guest configuration, showing all the available options, including Guest Additions for both 32-bit and 64-bit systems, Windows and Linux alike - and even Solaris, not surprising, considering VirtualBox owned by Sun. On most modern Linux distros, the system will auto-mount CD-ROMs and launch file browsers / managers.

Choose the right package for your hardware architecture. In our case, this is x86. Open a terminal window and run the script with root privileges:

sudo sh ./

See image:

Wait a few moments until the installation is complete. Reboot.

And that's it!

Debian live, one of many kinds

so what is a linux live CD???

A Debian Live system is a Debian operating system that does not require a classical installer to use it. It comes on various media, including CD-ROM, USB sticks, or via netboot. Why Debian Live?
Although the Debian Live project is about the framework to create your own customized Live system, we offer some prebuilt images. Currently, builds for three desktop environments (GNOME, KDE and Xfce) as well as the standard system are available.
