AttributeError: module 'numpy' has no attribute 'int'.
`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:\n    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations. Did you mean: 'inf'?

Steps To Reproduce

1. On fresh LXC Debian 12
2. Try to install using latest ansible role

Expected behavior
venv is used so all packages should have pinned or bounded versions to prevent such problems.

When numpy is downgraded in venv:

/opt/openwisp2/env/bin/pip install numpy==1.23.5

then ansible role can be started again and everything works.

Try with the latest master, the latest released version is not compatible with Debian 12.

[supersebbo]

Same error, Debian 12. Did you resolve this by using Master?

The 22.05 release is not compatible with Debian 12. Use the development version as already suggested.
