Installation fails due to SetuptoolsDeprecationWarning: License classifiers are deprecated.

Deployment Type

Self-hosted

NetBox Version

v4.3.0

Python Version

3.12

Steps to Reproduce

I run Ubuntu 24.04.2 LTS with python 3.12.3 and followed the official installation guide step by step.

As source I used git and checked out the current release (4.3.0). When I run sudo /opt/netbox/upgrade.sh, I get

Building` wheels for collected packages: psycopg-c
  Building wheel for psycopg-c (pyproject.toml) ... error
