Once again, I am facing the same problem mentioned in a previous report on July 5th; the problem has not been solved since then, I just postpone it ... The installation process works fine with a first module, but the following module bugs systematially and I get the message
AssertionError: The report "report.stock.picking.list" already exists!
Can anyone help please? I desperately need to have a complete configuration for teaching purpose in the next weeks.
