Рекомендуется использовать виртуальное окружение и Python 3.10:

Если у вас не скачен питон этой версии, сначала выполните:

```
|

sudo apt install python3.11 python3.11-venv

sudo apt install python3.10 python3.10-venv

Если у нас не устанавливается питон 3.11, то это потому что он отсутствует в официальных репозиториях по умолчанию, надо добавить репозиторий перед скачиванием:
