error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
python3-xyz, where xyz is the package you are trying to
install.

If you wish to install a non-Debian-packaged Python package,
create a virtual environment using python3 -m venv path/to/venv.
Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make

it may be easiest to use pipx install xyz, which will manage a

OK, if you try to run the VDI client, what imports does it claim are missing?

[lasseo]

The problem is that Ubuntu no longer allow Python modules to be installed via PIP.
https://www.omgubuntu.co.uk/2023/04/pip-install-error-externally-managed-environment-fix
So, the requirements script will completely fail, and hence it will be missing all these dependencies.

[jpattWPC]

Correct, but if you try to run the actual vdiclient.py file, what is the error message it displays?

ModuleNotFoundError: No module named 'PySimpleGUI'

No DEB package available to install PySimpleGUI

[joshpatten]

I don't think there's a .deb package for PySimpleGUI, but you can install it this way if you're willing to accept the risk of a potential package break in the future:

First, ensure tkinter is installed:

apt install python3-tk

Then force override the installation of pysimplegui:

pip install --break-system-packages PySimpleGUI
