Вопрос по установке gstreamer на Ubuntu 18.04

Я недавно обновился до Ubuntu 18.04, и DVD-плеер перестал работать. После некоторых исследований я пытался переустановить gstreamer, но столкнулся с проблемой, которая, похоже, связана с Ubuntu 18.04 и которая мне не понятна. Вот вывод команды:

$ sudo apt-get install gstreamer1.0-tools gstreamer1.0-alsa gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gstreamer1.0-plugins-bad : Depends: libgstreamer-plugins-bad1.0-0 (= 1.14.0-1ubuntu1) but 1.14.1-1ubuntu1~ubuntu18.04.1 is to be installed

Любая помощь очень ценится (особенно детьми:))
