Virtualbox Guest Additions Linux
If you experience issues with installing the Virtualbox Guest Additions it could be that the build environment, dkms or kernel headers are not installed.
Messages typically look something like the following:
/tmp/vbox.0/Makefile.include.header:97: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR= and run Make again. Stop
Install the following packages and retry the Guest Additions install:
# apt-get install build-essential dkms linux-headers-generic
