@joe-dunster - yes, it should be fixed but you will need to run an upgrade before you get the fix, it won't be in the main images until we make new ones at 16.04.1 (July). It will appear in the daily images though. If you downloaded the image from http://releases.ubuntu.com/16.04/ubuntu-16.04-desktop-amd64.iso then please run from the terminal:
sudo apt update
sudo apt upgrade
You should then get the new version of Software with the fixes to allow you to install a .deb.
