Hey 👋🏻 Thanks for raising this issue! Typically, these errors indicate that the Python installation on your system is not complete. Do you have python3.12-dev installed? (sudo apt-get install python3.12-dev)

Truly annoying how hard it is to properly set up Python even these days...

lukas-gerster commented 23 hours ago

python3-dev is installed, but there seems to be some kind of issue:

❯ sudo apt install python3-dev

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libpython3.12-dev : Depends: libpython3.12-stdlib (= 3.12.3-1ubuntu0.2) but 3.12.4-1+jammy1 is to be installed

I tried --fix-broken but it is not able to resolve the issue

Yeah. Unfortunately, your Python installation seems broken. It's definitely not the first time that I have seen this... IIRC, I personally fixed this at some point by doing a complete reinstall of all Python-related system packages.

We do run CI on default Ubuntu images in GitHub actions and everything seems to "just work" there as well as locally on multiple development setups.

You could give uv (https://docs.astral.sh/uv/) a try:

curl -LsSf https://astral.sh/uv/install.sh | sh
uv venv --python 3.12
uv pip install -e.

You can tell uv to explicitly set up Python for you and not use the system Python via

uv venv --python 3.12 --python-preference only-managed
