Modern debian (ubuntu) and fedora block users installing using pip.

Even if you're telling it to install in ~/.local? I could see not allowing
to run it as root.
I assumed pip install --user would work, but no. I tried it (on Debian
12 (bookworm)):
$ pip install --user docopt
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.
Exactly the same output for sudo pip install.
For easy reference here's a link to that PEP 668:
