Fresh install not working

[chanchel]

I have a completely fresh Ubuntu 22.04 installed with apache2 and python 3.10.12. the ./configure works but when I run make it gives me:

python3-dev is already installed, double and triple checked it.

What do you get when you run:

which python3

Does it come from a virtual environment or main system installation?

If a virtual environment, was it created before or after the python3-dev package was installed.

Can you also try the pip install method for installing mod_wsgi. See:
