Problem inizializing sqlite db with tryton 6.1.0

Could you share the error log? Then we may try to find a solution :wink:

Hehe, yes… but it’s a triky one.
Tox passes if I use trytond 5.8.0, but fails for tryton 6.0.0 and 6.1.0.
Tox fails in the database initialization, sqlite and postgres (with enviroment py39-sqlite and py39-postgresql).
If I cahnge the version to 6.1.0 and I try to initializate the db manually with

export TRYTOND_DATABASE__URI=sqlite://
trytond-admin -d test10 --all -vvv

sqlite fails with: (NOTE, by just change the package version to 5.8.0, sqlite will inizializate without error)

Traceback (most recent call last):

postgres will inizialize fine manually (in 6.1.0) with:

export TRYTOND_DATABASE__URI=postgres://postgres:<password>@localhost:5432/
trytond-admin -d postgres --all -vvv

I need to investigate further, @pokoli do you know the command tox lauch for setting up the env (or you know a way to increase the verbosity) it would help.

Ok, solved.
After digging the sources I stumble uppon how increase the verbosity of the unit test:
python -m -vv -m association
This made me realize that Sequence in tryton 6.1 changed a bit. (for future reference: issue2349)
