UTAH fails to install trusty ISO using default-preseed.cfg

[Diogo Matsubara]

I tried to run the following:

sudo -i -u utah run_utah_tests.py -d -i /media/matsubara/BACKUP/ubuntu-isos/trusty-server-amd64.iso -p /etc/utah/default-preseed.cfg /usr/share/utah/client/examples/master.run

and got a failure to install the ISO.

To workaround the issue I edited /etc/utah/config and changed the installpackages variable to use gdebi-core instead of gdebi since this is a server ISO install and the installation proceeded further.
