[Openstack] [Liberty] Nova does not start in compute node

Hi all,
I moved from kilo to liberty using devstack.
My local.conf scripts were working with kilo.
I have a multinode setup and, with a control node and a compute node.
But when I stack the compute node it is not in the nova service-list.
Bridges br-int and br-ex are created correctly.
These are the services enabled in my local.conf:

enable_service nova n-cpu quantum n-novnc rabbit

So I expect the logs and screens related to these services.

I was looking for the logs and there are just n-cpu.log and n-novnc.log (so
n-api is missing, also in the screens).

n-cpu.log says:

silvia at devstack2:~/devstack$ sg libvirtd '/usr/local/bin/nova-compute
ile /etc/nova/nova.conf' & echo $! >/opt/stack/status/stack/n-cpu.pid; fg
|| ech
o "n-cpu failed to start" | tee "/opt/stack/status/stack/n-cpu.failure"

    from nova import wsgi
  File "/opt/stack/nova/nova/wsgi.py", line 34, in <module>
    from paste import deploy
ImportError: cannot import name deploy
n-cpu failed to start

Any suggestions?
Thank you
