i installed Ubuntu 22.04 (fresh installation) an create an virtualenv with Python 3.10.
The installed packages are as follows:
libpython3.10:amd64
libpython3.10-dbg:amd64
libpython3.10-dev:amd64
libpython3.10-minimal:amd64
libpython3.10-stdlib:amd64
python3.10
python3.10-dbg
python3.10-dev
python3.10-minimal
python3.10-venv
When I try to install the application requirements file I see this error:

any ideas??
I have tried reinstalling the Python installation packages but the problem persists, I have read some publications and indicate that the problem may be caused because there are no headers related to the python dev package.
Most probably cffi==1.14.0 is not compatible with Python 3.10. Try the latest version:
pip install cffi==1.15.1
