Hello everyone.
I installed openerp like «aptitude install openerp» from this repositories: http://nightly.openerp.com/
Then, I downloaded jasper report from https://www.odoo.com/apps/6.0/jasper_server/
I searched for the openerp path and I found that the addons folder where at /usr/share/pyshared/openerp/addons/ so I moved the jasper directory to that place.
Then I clicked to the updating modules menu but the jasper module didn't appear.
I would really appreciate any kind of help because I really need to do that. Thank you very much.
