Installation following the documentation not possible on Debian 12 Bookworm

[etkaar]

An installation on Debian 12 Bookworm following the documentation is not possible. Using pip install -r requirements.d/prod.txt will cause following error message:

root@nsupdate:~# pip install -r requirements.d/prod.txt
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.

Using pip install nsupdate will lead to the same error message:

root@nsupdate:~# pip install nsupdate
error: externally-managed-environment

    python3-xyz, where xyz is the package you are trying to

Finally using pipx install nsupdate will cause following error message:

root@nsupdate:~# pipx install nsupdate
Note: Dependent package 'netaddr' contains 1 apps
  - netaddr
Note: Dependent package 'django' contains 1 apps
  - django-admin
Note: Dependent package 'sqlparse' contains 1 apps
  - sqlformat
Note: Dependent package 'charset-normalizer' contains 1 apps
  - normalizer

No apps associated with package nsupdate. Try again with '--include-deps' to include apps of dependent packages, which are listed above. If you are attempting to
install a library, pipx should not be used. Consider using pip or a similar tool instead."

Maybe rather work:

• as a user (not root)
• in a python virtual env

See top of the page there:

Also, guess using git master branch would be better for production, the last release was quite a while back. But you can do first experiments also with the pip package.
