Run ./unstack.sh
Create a kind of local.conf bellow under devstack
This version will install neutron.

# Services
disable_service n-net
enable_service n-cauth
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service horizon

Either run :-
$ sudo ./unstack.sh
$ sudo reboot
Rerun ./stack.sh with local.conf above
Actually, it would be new fresh install with neutron.
