Oracle JDK 7 is NOT installed.
dpkg: error processing oracle-java7-installer (--configure):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 oracle-java7-installer
E: Sub-process /usr/bin/dpkg returned an error code (1)

Já pesquisei na internet e encontrei alguma solução que funcionasse para as pessoas:

sudo rm /var/lib/dpkg/info/oracle-java7-installer*
sudo apt-get purge oracle-java7-installer*
sudo rm /etc/apt/sources.list.d/*java*
sudo apt-get update
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer

e

sudo dpkg -P oracle-java7-installer
sudo apt-get -f install
sudo apt-get install oracle-java7-installer

mas nenhum deles funcionou para mim. Ainda receba a mesma mensagem. Alguém poderia me ajudar com isso?

Por favor, siga os passos abaixo para instalar o Oracle java:

• Faça o download da versão mais recente do Java SE SDK.

  link

• Descompacte o arquivo:

  tar -xzvf /root/jdk-7u17-linux-x64.tar.gz
  mv jdk1.7.0_17 /opt
  cd /opt/jdk1.7.0_17
  

• Esta etapa registra a versão baixada do Java como uma alternativa e a alterna para ser usada como padrão:

  update-alternatives --install /usr/bin/java java /opt/jdk1.7.0_17/bin/java 1
  update-alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_17/bin/javac 1
  update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /opt/jdk1.7.0_17/jre/lib/amd64/libnpjp2.so 1
  update-alternatives --set java /opt/jdk1.7.0_17/bin/java
  update-alternatives --set javac /opt/jdk1.7.0_17/bin/javac
  update-alternatives --set mozilla-javaplugin.so /opt/jdk1.7.0_17/jre/lib/amd64/libnpjp2.so
  

• Teste

  Para verificar a versão do Java que você está executando agora

  java -version
