$ pip3 install yamllint
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
    sure you have python3-full installed.
    
    If you wish to install a non-Debian packaged Python application,
    it may be easiest to use pipx install xyz, which will manage a
    virtual environment for you. Make sure you have pipx installed.
    
    See /usr/share/doc/python3.11/README.venv for more information.
note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.
hint: See PEP 668 for the detailed specification.

Reason: pip install -r requirements.txt is failing: This environment is externally managed

Solution:

• guide-users-towards-virtual-environments
• for applications/executables use pipx:
  • sudo apt install python3-full pipx
  • pipx install yamllint
• for others ise venv

Dirty solution (but usefull for Dockers or CI):

• sudo rm /usr/lib/python3.11/EXTERNALLY-MANAGED
