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:

  Any clue will be welcome !
