Problemas ao instalar python3.11-venv no debian 12

Estou tendo alguns problemas tentando fazer o virtualenv funcionar no debian 12, é difícil decifrar qual é exatamente o problema. Eu executei apt updatee apt upgradetambém, é uma instalação de rede nova do Debian de apenas alguns dias atrás.

$ 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

Qualquer dica seria útil, é difícil saber se isso é apenas um problema de empacotamento do Python ou se talvez eu precise me concentrar mais no erro exato python3.11-venv : Depends: python3.11 (= 3.11.2-6+deb12u2) but 3.11.2-6+deb12u3 is to be installed.

https://tracker.debian.org/pkg/python3.11 também afirma algo preocupante:

pacote desapareceu Este pacote não está em nenhum repositório de desenvolvimento. Isso provavelmente significa que o pacote foi removido (ou foi renomeado). Portanto, as informações aqui são de pouco interesse... o pacote vai desaparecer a menos que alguém o tome e o reintroduza.
