I have the same issue, but with setup and more info :

sudo run_foreman.py setup /home/foreman/config/config.ini

config.ini changed :

database_name = foreman

port_number = 5432

database_type = postgres

database_location = localhost

...

website_domain = http://foreman:5000/

>>> exit()

I suppose that the new version of monthdelta with does this ¯\(ツ)/¯ , the question is maybe witch version to use?

==================Machine info==================

All installed with setup.py

monthdelta version = 0.9.1

I use a vm of ubuntu-serveur 16.04 LTS (so every code is manualy write, sorry for mistakes)

Thanks for answer

I think i have figured out, it is strange that setup.py install the 0.9.1 version and not the 1.0b

this seems to correct it :

sudo pip uninstall monthdelta
sudo pip uninstall monthdelta==1.0b
sudo pip install -Iv monthdelta==1.0b
