I am pretty sure this is a duplicate of #1546459 . Downloading a new netinstall from trusty-updates (not trusty) seems to fix the problem. In particular I used the following:
open http://ca.archive.ubuntu.com/ubuntu/dists/trusty-updates/main/installer-amd64/current/images/netboot/ubuntu-installer/
I had not realized that there was a new version of the installer because I was looking in the wrong directory.
