Python error during eSim2.3 on Ubuntu 23.04

Hi,

I'm trying to install eSim2.3 on a fresh and updated Ubuntu 23.04. I'm quiet a newbe with the terminal / Ubuntu, but forced to use it to install eSim2.3

After using these lines, $ chmod +x install-eSim.sh and $ ./install-eSim.sh --install I got a seemingly Phyton error. Is there a way to solve this easily?

Ps, in about a week I got more time to play around with stuff, now waiting for a new hip and need the pc in hospital. Afraid to screw things up.

Thanks in advance.

× 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.
