[tryton-debian] Bug -> Tryton 4.2.1 - Debian 9.3

[Gonzalo Gutierrez]

Hello.

I am trying to use Tryton 4.2.1 (demo profile) in Debian 9.3, but the
following error message appears:

*"Error: Database4.2.sqlite doesn't exist!*

*Traceback (most recent call last):*
*  File "/dist-packages/trytond/wsgi.py", line 47, in dispatch_request*
*    return endpoint(request, **request.view_args)*
*  File "/dist-packages/trytond/protocols/dispatcher.py", line 41, in rpc*
*    request, database_name, *request.rpc_params)*
*  File "/dist-packages/trytond/protocols/dispatcher.py", line 48, in login*
*    Database(database_name).connect()*
*  File "/dist-packages/trytond/backend/sqlite/database.py", line 220, in
connect*
*    raise IOError('Database "%s" doesn\'t exist!' % db_filename)"*


What can be done to solve that?

Thanks.
