Describe the bug Installing maestral as described in the documentation results in an error ModuleNotFoundError: No module named 'importlib_metadata' when the maestral executable is run.

Full output:

ModuleNotFoundError: No module named 'importlib_metadata'

To Reproduce

1. Install maestral in a Python venv as described in the installation instructions:

$ python3 -m venv maestral-venv
$ source maestral-venv/bin/activate
(maestral-venv)$ python3 -m pip install --upgrade maestral

2. Run the maestral executable from the venv, with no arguments

Expected behaviour Maestral should print usage information

System:

• Maestral version: 1.8.8
• Python version: 3.12.1
• OS: fedora 39
• Desktop environment: Gnome 45.4
• PyQt version (for Linux GUI): n/a

Additional context

maestral works as expected after manually installing importlib-metadata with pip install importlib-metadata.
