Не удается установить файл deb (также через графический интерфейс и терминал) (Ubuntu 18.04)

Пытаюсь установить YouTube To MP3 заявка на Ubuntu 18.04 который работает на моем Ubuntu 16.04 без проблем.

Когда я дважды нажимаю на deb файл, он работает GUI установщик, но когда я нажимаю на install, он начинает установку, затем останавливается и не показывает ошибок, кроме install Кнопка все еще там.

Поэтому я пытаюсь установить его вручную, но есть и ошибки. Я покажу вам здесь мои шаги:

milano@milano-PC:~/Downloads$ sudo dpkg -i youtube-to-mp3-converter3-9-4-64-bit.deb 
[sudo] password for milano:

Так что проблема в том, что на нем не установлены зависимости:

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libqt4-declarative : Depends: libqt4-network (= 4:4.8.7+dfsg-7ubuntu1) but it is not going to be installed
                      Depends: libqt4-script (= 4:4.8.7+dfsg-7ubuntu1) but it is not going to be installed

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

Итак, я делаю:

Затем, когда я пытаюсь установить приложение снова, первый шаг происходит снова.
