Hi Mike,

If I understand your question correctly you're getting this when installing / adding a module. This error is telling you that the library passlib.utils is missing. So simply install it inside your Ubuntu like this:

sudo pip install passlib

Update your Odoo after adding the library (by -u) and it should be fixed.


wow "pip" is that magic. many thanks

Got to love pip for these cases. No problem, best of luck with Odoo 9!

You need to install all the requirements for Odoo v9 and better use a virtual enviroment for that because if you install all the requirements for Odoo v9 in the same system probably you will break the OpenERP instances that you have running. To do it check this answer:
