I am trying to install Devstack on Ubuntu 12.04 (64 bit) and stack.sh crashes with this error:

The log file has the same information. It also has this error for keystone:

2013-06-14 11:54:44 Configuration error: Client configured to run without a service catalog. Run the client using --os-auth-url or OS_AUTH_URL, instead of --os-endpoint or OS_SERVICE_ENDPOINT, for example.

It seems that keystone is not configured properly. That causes the OS_AUTH_TOKEN to be empty. Any idea why?
