Comment 24 for bug 1460653

Big Switch Networks, thanks, I've taken a look into your snapshot.

Ubuntu images were built without any errors, but took 1.5h. Deployment has been failed due to timeout expiration. Fuel expects that image will be built within 1h.

It may be unstable or low bandwidth connection to official ubuntu repos hosted at http://archive.ubuntu.com/ubuntu/

Unfortunatelly, it has nothing to deal with fuel itself.

In order to bypass that, you could just try to re-deploy of the same env again.
The building of image will continue in a background even the task was timed out.
Please be aware, that ubuntu images are going to be build on once per env basis.
