Не удалось установить icedtea плагин на Единороге Utopic 14.10

Попытка установить icedtea-7-plugin на 14,10 x64 дает ошибку.

apt-get install icedtea-7-plugin
. . .
Selecting previously unselected package icedtea-netx:amd64.
. . .
Processing triggers for man-db (2.7.0.2-2) ...
E: Sub-process /usr/bin/dpkg returned an error code (1)

Кажется, что существует проблема с зависимостью, icedtea-netx. Таким образом, я пытался установить icedtea-netx просто отдельно, и ошибку показывают ниже.

Это, казалось, искало java-8-openjdk-amd64. Я установил openjdk-7-jre из репозиториев, таким образом, я удалил это и установил и openjdk-8-jre и openjdk-8-jdk. Однако это не исправляло проблему с icedtea-netx.

(Я хочу использовать icedtea и открыть JDK, не собственный Java от Oracle).

Кто-либо испытал это и является там разрешением к проблеме?

Вот вывод apt-get install icedtea-netx...
