I have a virtual box running Ubuntu 10.04 LTS. I updated the system every few weeks or months, but I had been having trouble due to the adobe-flashplugin removal always erring out.
Did some searching on the interwebs and got to a forum on crunch bang linux. Read through it, tried some of the suggestions and finally hit the solution. There was a file, adobe-flashplugin.prerm, that was horking the script. Deleting it, as one commenter wrote, took care of the problem. And now I'm on my way to being able to update my system.
