With uv, I can install and run python 3.13 and Django 5.2.8 and it was entirely trivial.

If you want to try, delete pyproject.toml and replace it with this:

[project]
name = "etebase"
version = "0.1.0"
description = "Add your description here"
readme = "README.md"
requires-python = ">=3.11"
dependencies = [
    "aiofiles>=25.1.0",
    "django>=5.2.8",
    "fastapi>=0.121.3",
    "msgpack>=1.1.2",
    "pydantic>=2.12.4",
    "pynacl>=1.6.1",
    "redis>=7.1.0",
    "typing-extensions>=4.15.0",
    "uvicorn[standard]>=0.38.0",
]

Let me know if it works for you.
