Webupd8 Oracle Java8 no rpi faltando javaws.policy

Question

Estou tentando instalar o Oracle java8 no meu raspberry pi 3.

Meu script segue as instruções no link . Eu tentei tanto a opção de baixar o tar e permitir que o instalador faça o download automaticamente. Ambos resultam no mesmo erro:

$ sudo apt-get install oracle-java8-installer

dpkg: error processing package oracle-java8-installer (--configure):
 subprocess installed post-installation script returned error exit status 1

Observe a linha abaixo, que acho que é a causa do erro.

mv: cannot stat '/usr/lib/jvm/java-8-oracle/jre/lib/security/javaws.policy': No such file or directory

Eu pesquisei extensivamente e não consigo encontrar nenhuma menção a isso em nenhum lugar nas interwebs.

Estranhamente, eu provisionei dezenas de Pis com este script há alguns meses e - embora também tenha sido uma dor de cabeça por outras razões - eu não tive esse problema.

Alguém tem alguma ideia? Ou pode me apontar para um fórum / canal do irc onde pessoas que possam ter uma ideia podem ser encontradas?

Felicidades, muito apreciadas

    

Answer 1

Por algum motivo, este arquivo deve ser deixado de fora da instalação. Talvez você pudesse esperar que eles consertassem a distribuição. Eu escrevi um pequeno script que observava a criação do diretório de destino e, em seguida, soltei um arquivo javaws.policy nele.

while [ ! -d "/usr/lib/jvm/java-8-oracle/jre/lib/security/" ]
  do
  sleep 1
  done
cp javaws.policy /usr/lib/jvm/java-8-oracle/jre/lib/security/

Eu iniciei este script antes da instalação / atualização em uma janela, depois fiz a instalação / atualização em outra janela.

Este é o conteúdo do javaws.policy que criei:

grant codeBase "file:${jnlpx.home}/javaws.jar" {
    permission java.security.AllPermission;
};

Não estou muito preocupado com o conteúdo, pois duvido que usarei o Java WebStart nesta plataforma.
