My issue is that the installation always stop with "2017-01-17 09:24:23.803 | cp: cannot stat '/opt/stack/tacker-horizon/openstack_dashboard_extensions/*': No such file or directory". I remove the tacker-horizon folder, then manually install it via git clone, it does not work.

i have no clue to move forward now, can some one give me any comments here ?

thanks !
