Неудовлетворенные зависимости при попытке установить Unity Tweak Tool [duplicate]

Я использую Ubuntu 16.04. Я попробовал большинство методов, но ни один не работает. Обратите внимание, что я использовал метод удаления Unity Tweak Tool, но он не сработал.

Я постоянно получаю это сообщение и удалил большинство пакетов.
