在 Debian 12 上安装 python3.11-venv 时遇到问题

我在尝试让 virtualenv 在 Debian 12 上运行时遇到了一些问题，很难弄清楚到底是什么问题。我已经运行过了，apt update而且apt upgrade这是几天前刚刚在网络上安装的 Debian。

$ python3 -m venv code_execution_env
The virtual environment was not created successfully because ensurepip is not
available.  On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.

    apt install python3.11-venv

You may need to use sudo with that command.  After installing the python3-venv
package, recreate your virtual environment.

Failing command: /home/chris/projects/claude-engineer/code_execution_env/bin/python3

$ sudo apt install -y python3.11-venv

我也尝试过python3-venv，python3.11-full但没有成功：

$ sudo apt-get install python3.11-full

apt-缓存策略：

$ apt-cache policy python3.11 python3.11-venv
python3.11:

尝试过apt --fix-broken install：

任何指示都会有帮助，很难知道这是否只是一些 python 打包问题或者也许我需要进一步关注确切的错误python3.11-venv : Depends: python3.11 (= 3.11.2-6+deb12u2) but 3.11.2-6+deb12u3 is to be installed。
