Ошибка при запуске pwntools в Ubuntu 18

Я использую Ubuntu 18 с 64b.

Чтобы установить pwntools , я выполнил:

$ sudo apt install python3 python3-pip python3-dev git libssl-dev libffi-dev build-essential
$ sudo python3 -m pip install pwntools

Когда я запускаю pwn , я получаю следующие ошибки:

$ pwn

Как мне исправить это запустить pwntools?
