package grub-efi-amd64-signed 1.34.2+2.02~beta2-9ubuntu1.1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 1

[Robert Hoey]

Software Update failed on 2015/05/13 to load or install part of the update package for Ubuntu 14.04 LTS, specifically, flashplugin-installer.

A second attempt, run on request automatically through the terminal, seems to have succeeded in installing the missing flashplugin. So I am not sure this counts as a bug.
