initialize database

trytond-admin -c /etc/tryton/trytond.conf -d tryton_test --all
“admin” email for “tryton_test”: YOURMAIL@YOUKNOWHAT.COM
“admin” password for “tryton_test”: snafu
“admin” password confirmation: snafu

run trytond

trytond -c /etc/tryton/trytond.conf

run tryton client

Host: localhost
Database: tryton_test
username: admin

password: snafu

FYI, Tryton is packaged on Ubuntu.

I was aware of that, but did’nt succeed now i start to understand why. als so i needed the 5.2 version to compaire,

A post was split to a new topic: Failed to build PyGobject

Hi Cedric,

I followed up your advice and switched distro to armbian with Buster.
I then tried the tryton package that comes with this but this did not work as I was expecting an out of the box solution (like docker) but I had to setup database etc which I did not get to work.
I then moved over to installing through pip using the instructions on Installing tryton(d) 5.2* on ubuntu 18.04.3 with postgres 11 for newbys by newby
Here I got stuck at the section ‘sudo -u postgres psql’ where I got the system error:
could not change directory to “/root”: Permission denied
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket “/var/run/postgresql/.s.PGSQL.5432”?

I hope you are able to assist me on this?
I must admit that it’s quite daunting to setup Tryton in this way when you are not a tech guy like me and just want to test Tryton…
Anyway I hope you can help.

Regards, Wil

As you run sudo from root without loading shell specification, the $HOME stays the root home. And as psql needs to write on the home directory, it fails because postgres user has no write permission on this directory.
Indeed you must run sudo -i -u postgres psql to force loading the shell specification.

Use the docker image like @pokoli sugested this is a the simplest way.
Installing tryton on a specific OS manually requires knowledge in UNIX, Python, PostgreSQL etc.

1.I tried sudo -i -u postgres psql and received this error message:
sudo -i -u postgres psql
psql: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket “/var/run/postgresql/.s.PGSQL.5432”?

2.I will also give docker a try but I believe from our previous discussion that although docker works on buster it can NOT work on an ARM architecture. I might be wrong though?

It sounds like your PostgreSQL service is not running.
sudo service postgresql start

Hope that helps

when I try to initialize database I got error "psycopg2.OperationalError: FATAL: password authentication failed for user “tryton_test”

maybe someone can help?

The credentials you are using to connect to postgresql database are not valid.

Hi, I reinstalled Tryton this time according steps described here. It worked one time, but next time I tried to run Tryton client got the error "tryton.jsonrpc.Fault: relation “ir_cache” does not exist
LINE 1: SELECT “a”.“timestamp”, “a”.“name” FROM “ir_cache” AS “a”

Fault: relation “ir_cache” does not exist
LINE 1: SELECT “a”.“timestamp”, “a”.“name” FROM “ir_cache” AS “a”
and “tryton.jsonrpc.Fault: ‘res.user’”
So I succeeded to initialize database but now something wrong with authentication
