package libgl1-mesa-glx 10.3.2-0ubuntu0.1 failed to install/upgrade: 65.8474:subprocess installed post-installation script returned error exit status 2

On upgrade from 14.04 to 14.10, libgl1-mesa-glx:amd64 caused everything to fail. What I did to fix was run:

sudo dpkg --force-all --configure libgl1-mesa-glx

but it gave me an error that it couldn't delete /etc/ati because it was a directory. Deleted that directory, tried again, worked. Continued with:

sudo dpkg --configure -a

and all seems well now.
