package linux-image-3.5.0-49-generic 3.5.0-49.73~precise1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[John Hendrich]

During update, process hangs (specifically update-grub). Tried killing the process and running dpkg --configure -a to recover but that attempt hangs as well.
