mhn install fails on linux ubuntu 18.04

I am trying to install mhn(modern honey network) on a fresh install of ubuntu 18.04

I got these errors.

Initializing` database, please be patient. This can take several minutes

python initdatabase.py Traceback (most recent call last): File "initdatabase.py", line 5, in create_clean_db() File "/opt/mhn/server/mhn/init.py", line 116, in create_clean_db db.create_all() File "/opt/mhn/env/lib/python2.7/site-packages/flask_sqlalchemy/init.py", line 963, in create_all self._execute_for_all_tables(app, bind, 'create_all') File "/opt/mhn/env/lib/python2.7/site-packages/flask_sqlalchemy/init.py", line 955, in _execute_for_all_tables op(bind=self.get_engine(app, bind), **extra) File "/opt/mhn/env/lib/python2.7/site-packages/flask_sqlalchemy/init.py", line 896, in get_engine return connector.get_engine() File "/opt/mhn/env/lib/python2.7/site-packages/flask_sqlalchemy/init.py", line 556, in get_engine self._sa.apply_driver_hacks(self._app, info, options) File "/opt/mhn/env/lib/python2.7/site-packages/flask_sqlalchemy/init.py", line 861, in apply_driver_hacks info.database = os.path.join(app.root_path, info.database) AttributeError: can't set attribute```
