Não foi possível instalar o plugin icedtea no Utopic Unicorn 14.10

Tentar instalar o icedtea-7-plugin no 14.10 x64 apresenta um erro.

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)

Parece que há um problema com uma dependência icedtea-netx,. Então, eu tentei instalar icedtea-netxsozinho, e o erro é mostrado abaixo.

Parecia estar procurando java-8-openjdk-amd64 . Eu tinha instalado o openjdk-7-jre a partir dos repositórios, então desinstalei e instalei o openjdk-8-jre e o openjdk-8-jdk. No entanto, isso não corrigiu o problema com icedtea-netx.

(Quero usar o icedtea e abrir o JDK, não o Java proprietário da Oracle).

Alguém já experimentou isso e existe uma solução para o problema?

Aqui está a saída de apt-get install icedtea-netx...

Tentei com êxito outra solução temporária.

A mensagem de erro diz: "alternativas de atualização: erro: o caminho alternativo / usr / lib / jvm / java-8-openjdk-amd64 / jre / bin / javaws não existe". Então, eu criei um link simbólico e desinstale um por um os pacotes (icedtea-plugin, icedtea-7-plugin e icedtea-netx (não é necessário para icedtea-netx-common)), depois reinstale o icedtea-plugin.

cd /usr/lib/jvm
ln -s java-1.7.0-openjdk-amd64 java-8-openjdk-amd64
apt-get purge icedtea-plugin
apt-get purge icedtea-7-plugin
apt-get purge icedtea-netx
apt-get install icedtea-plugin

Eu tenho o mesmo problema e assumi que este é um erro no pacote. Eu relatei isso . Como solução alternativa, segui as instruções sobre a instalação do Oracle Java .

Basta seguir a solução do problema fornecida em https://bugs.launchpad.net/ubuntu/+source/icedtea-web/+bug/1385478 .

Parece funcionar muito bem.

Se você possui o openjdk 7 e 8 instalado, basta ligar o javaws e itweb-settings e reinstalar o icedtea-plugin, icedtea-7-plugin e icedtea-netx

sudo ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/javaws /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/javaws$
sudo ln -s /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/itweb-settings /usr/lib/jvm/java-8-openjdk-amd64/jre/bin/itweb-settings
