Hello, I love to be here. I installed a similar version of Odoo 8.0.20160729 (which i try to run now on my machine) on another machine. It worked without problems and i really love it.

Specs. recent machine:

Odoo 8.0.20160729 with "PostgreSQL 9.3.5, compiled by Visual C++ build 1600, 32-bit"

pgAdmin 1.18.1

Firefox 47.0

User "Hörner-PC/Hörner" in Win 10 home on a x64 machine


I cant login into Odoo: "500 Internal Server Error". I reinstalled Odoo in different folders (last: "C:\Odoo8"). Before the reinstallation i cleansed my pc of the old installation. Running openerp_server.exe in cmd showed an encoding error ([1] - UnicodeEncodeError). [2] led to a solution (unset client_encoding in postgresql.conf , restart service PostgreSQL_for_Odoo) . This led to the next Error ([3] - "no password supplied"). Solved by [4] (pg_hba.conf - for all IPv6 local connections: replaced "md5" with "trust"). Which led to ([5] - role doesn't exist, showing encryption errors). I am not sure if this is a problem with encoding or with a nonexisting user.

[1] - "UnicodeEncodeError: 'ascii' codec can't encode character u'\xf6' in position 10: ordinal not in range(128)"

[2] - https://github.com/odoo/odoo/issues/835

[3] - OperationalError: "fe_sendauth: no password supplied"

[4] - http://stackoverflow.com/questions/33928585/python-and-postgresql-operationalerror-fe-sendauth-no-password-supplied

[5] - OperationalError: FATAL: role �H�rner� doesn't exist


I could search on for solutions but i fear that this will lead to a series of other errors. Is there a general mistake i made, that leads to these errors?

Not beeing experienced in SQL, I didn't really understand the structure behind Odoo. What i understood: Odoo uses (in a way) PostgreSQL by using the user "openpg". This works: openpg is logged in localhost:5432 according to pgAdmin. But what does "INFO ? openerp: database user: Hörner" mean in this context?

Thanks very much

every help is appreciated!

INFO and ERROR messages are from the Odoo log and tell you a little bit about what's happening on the backend of things.

Do you mean that "Hörner-PC/Hörner" is supposed to be your internal Odoo database user? If yes, you have to provide me a taster of your dope :-)

In a standard Odoo installation, the internal Odoo database user is "odoo". You might well change that, even if I see no reason for it, but in that case please try to avoid any non-standard ASCII characters.

You can use pgadmin to create a new role with the supplied name [Hörner as in your case] by odoo log ...


or try to use the server parameters to enforce the db user:

--db_user <user here e.g openpg >, --db_password <password>

when you're running the server ...

hope this could helps

Thanks to all who helped or wanted to help!

The Error on the machine wasn't solved. I now use Odoo 8 on a virtual machine, which worked from the beginning.


Htm-Mbs, Travis Waelbroeck, Ermin Trevisan, Ahmed M.Elmubarak. Hello, grüetzi and As-salam alaykom! Thank you very much for your answers!

To make this clear: i did not use "Hörner-PC/Hörner" as username for Odoo. I do use "Hörner" to login to Windows. The name of my machine, my pc is "Hörner-PC". I never specified any username for using Odoo (i can't access it in any way, as mentioned above - 500 internal server error). The only username i was able to choose was the postgreSQL "openpg"-username during the Odoo all-in-one-installer installation. But I kept this standard username.

I didn't set any Odoo-specific username. If I understand correctly, odoo logs into postgreSQL by using usr "openpg" (see https://pl.vc/1i1zpy ). How come that i get

2016-07-31 08:19:07,546 8988 INFO ? openerp: OpenERP version 8.0-20160729
2016-07-31 08:19:07,546 8988 INFO ? openerp: addons paths: [u'C:\\Users\\H\xf6rner\\AppData\\Local\\OpenERP S.A.\\Odoo\\addons\\8.0', u'C:\\Odoo8\\server\\openerp\\addons']
2016-07-31 08:19:07,562 8988 INFO ? openerp: database hostname: localhost
2016-07-31 08:19:07,562 8988 INFO ? openerp: database port: 5432
2016-07-31 08:19:07,562 8988 INFO ? openerp: database user: Hörner
2016-07-31 08:19:08,891 8988 INFO ? openerp.service.server: HTTP service (werkzeug) running on

The database user differs from the one shown by pgAdmin. AND it is my windows username.

I tried to add the role "Hörner". It didn't work. I still get "OperationalError: FATAL: role �H�rner� doesn't exist".

This PC once was infedted by a virus. Is it possible that this scrambled the encoding?

Answer to Ermins comment from 31.07. 12:04:

this is the content of my openerp-server.conf:


addons_path = C:\Odoo8\server\openerp\addons

admin_passwd = admin

auto_reload = None

bin_path = C:\Odoo8\thirdparty

csv_internal_sep = ,


database user = openpg


user = openpg

won't change a thing

Hello Ermin, hello Ahmed,

thank you very much again for your answers. As soon as it's possible i'll give your ideas a try. As i'm not a my machine at the next days, it'll take a while.


Check your openerp-server.conf file, there you will find the database user and in your case it should be "openpg" and not "Hörner".

It must be:

db_user = openpg

db_password = False
