virtualbox.org

Upgrading from 3.06 to 3.08. I simply tried to install over the top as per faq, but got the following message:
"The following install step failed: run postflight script for Sun VirtualBox Kernel Extensions."
Can't open VB any more.
Where might I start...
Thanks,
Jeff

well, I started with the basically obvious step and did a reboot - and all is functioning normally. 3.08 is installed.
Any reason to be concerned?
