apt-get install python-dev не удалось устранить зависимость [дубликат]

Я не могу установить python-dev на свой сервер. ЦП - ARM64 ОС - Ubuntu16.04.03

Не удалось из-за неудовлетворенных зависимостей.

Я уже пробовал выполнить обновление, обновление, принудительную установку, и я использовал несколько ссылок для решения. Похоже, проблема специфична для ARM64 с ubuntu16.04.3 ...

# sudo apt policy python-dev
python-dev:
  Installed: (none)
  Candidate: 2.7.11-1
  Version table:
     2.7.11-1 500
        500 http://us.ports.ubuntu.com/ubuntu-ports xenial/main arm64 Packages

Я попытался вручную установить зависимый пакет python pkg, но не смог разрешить зависимость:
