Exception 'tryton' is not a Tryton database

Hello, everyone. Not sure that this is a good place to ask my question, but here it is.
I am installing for first time tryton on Ubuntu 20.04 with PostgreSql and during DB initialisation I am getting this:
raise Exception(’"%s" is not a Tryton database.’ % db_name)
Exception: “tryton” is not a Tryton database.
Same error with SqLIte.
I can give more details if needed.
If this is not a place to this question, please indicate where to post it.
Thank you
