Around the beginning of 2025, the `ubuntu-latest` runner image
which [this project uses][1], [was changed from Ubuntu 22.04 to 24.04][2].
As a result, the python version which is used by this repo's GitHub actions
changed from [3.10.12][3] to [3.12.3][4].
With this change to Python 3.12, [PEP 668][5] was introduced. This new Python
behavior is causing errors in the CI and `pip` is exiting non-zero
```
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/python3.13/README.venv for more information.
```
This adds a `--break-system-packages` argument to the `pip install` so that
it can continue to install packages without an error.
A possible future improvement would be to do these installations in a virtual
environment.

It looks like the CI is a bit out of date. I'll close this PR and come up with another one that fixes all of the CI issues. |
