Hello,

I am discovering Qlustar (being a ROCKS admin since a long time). My first test with Qlustar 10.x was sucessful; qluman-qt started correctly, I browsed the windows with no problem.

I reinstalled everything from scratch to run Qlustar 11, installed qluman-qt with apt install and using the singularity image : both version give the error

(...) File "/usr/lib/python3/dist-packages/sqlalchemy/engine/default.py", line 393, in connect return self.dbapi.connect(*cargs, **cparams) sqlalchemy.exc.OperationalError: (sqlite3. OperationalError) unable to open database file

I wonder why SQLITE3 is invoqued because during the installation, there was a prompt for mysql root's password. MariaDB is running, and a Qlustar Database exists and populated : mysql -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 48 Server version: 10.1.41-MariaDB-0ubuntu0.18.04.1 Ubuntu 18.04 Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others. Type 'help;' or '\h' for help. Type '\c' to clear the current input statement. MariaDB [(none)]> use Qlustar; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A

Any clue will be welcome !

Thanks
