When an old image is used to install a system, provisioning with UTAH fails with:
"ERROR: Failed to install client. Writing empty reports."

For example the log attached is the installation of Ubuntu Desktop 20121129 on Hardware:

This is blocking because recent images do not work on one of our configuration and we must use this specific image until the issue is found.
