Have you tried all the fix methods listed in the forum with regards to guest additions and vbox? Quite a common problem that I myself have had to deal with and posted a solution which was also taken and incorporated into a script.

However this may not fix your issue as I tried to update and couldnt get it to work once I did a dist-upgrade from R1-R2 (using my method or the script). For my particular situation I found it quicker and easier to re-download the latest VM image and installation of guest additions worked straight away with a clean image.

Not sure how much customisation you have but I didnt have that much so starting from scratch was not a problem, plus I had the piece of mind nothing I had screwed with in the past would affect anything now or in the future on the OS.
