package memtest86+ 4.20-1.1ubuntu1 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 1

I ran a wubi upgrade from 10.04.4 to 12.04. I created a separate bug report for the upgrade in bug 984593. I guess some of the errors I saw are reporting themselves ;) so I'll pass them on
