Many days ago, I install Odoo9.0 on my Debian8.4 OS according to "Odoo_Development_Cookbook"; All is ok.
Now some errors occur, I reinstall Debian and update it to version8.6; after that I install Odoo9.0 accroding to "Odoo_Development_Cookbook", then there are some errors about dependencies because of some packages' update;
How shall I resolve this problem?
Or is there some good methods to install Odoo?
