Constant Boot Looping when running under Debian

[rGunti]

After test-running MetaTube on my Win10 machine (using Docker of course) I tried setting up a VM/LXC where I can keep it permanently using the command provided in the README. Unfortunately the container seems to bootloop constantly. The log provides me with this error:

INFO  [alembic.runtime.migration] Context impl SQLiteImpl.
INFO  [alembic.runtime.migration] Will assume non-transactional DDL.
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/sqlalchemy/engine/base.py", line 1802, in _execute_context

  File "/usr/local/lib/python3.9/site-packages/sqlalchemy/engine/default.py", line 732, in do_execute
    cursor.execute(statement, parameters)
sqlite3.OperationalError: database is locked

The above exception was the direct cause of the following exception:

According to your error, the Database is locked. This means another process is using the database file. Perhaps your Docker container is still running and using the Database? Or you have opened the Database somewhere else?
