Ошибки во время установки Ubuntu-Limited-Extras

Во время установки ubuntu-restricted-extras, которая была инициирована с помощью этой команды:

sudo apt-get install ubuntu-restricted-extras

я получил следующие ошибки:

, что немного обеспокоило меня, так как кажется, удалил некоторые важные зависимости. Должен ли я беспокоиться об этом? И нужно ли что-нибудь с этим делать? Я использую Ubuntu GNOME 15.04.

Обновление информации:

При запуске sudo apt-get install -f на выходе не было проблем, и на выходе не было sudo dpkg --configure -a.
