Indicador de bateria ausente, não é possível instalar porque não há JDK 7

Question

Sou muito novo em todo o negócio do Linux, mas estou em um laptop e um medidor de bateria seria extremamente útil. Sempre que tento

sudo apt-get install indicator-power

isso me dá:

'Reading package lists... Done

Qualquer ajuda seria realmente apreciada!

@Braiam quando eu corri o primeiro comando para corrigir os repositórios, e ele voltou com:

Can't rename /etc/apt/sources.list.d/iaz-battery-status-quantal.list /etc/apt     /sources.list.disable.d/iaz-battery-status-quantal.list.disable: No such file or directory
Can't rename /etc/apt/sources.list.d/ubuntu-wine-ppa-quantal.list /etc/apt/sources.list.disable.d/ubuntu-wine-ppa-quantal.list.disable: No such file or directory
Can't rename /etc/apt/sources.list.d/webupd8team-java-raring.list /etc/apt/sources.list.disable.d/webupd8team-java-raring.list.disable: No such file or directory

@Braiam, agora quando eu corro com essa linha, depois de cada linha que eu digito, há essa resposta depois que tudo parece ter funcionado além disso:

N: Ignoring file 'ubuntu-wine-ppa-quantal.list.disable' in directory '/etc/apt/sources.list.d/' as it has an invalid filename extension

Answer 1

O problema é que você tem alguns repositórios mistos. Faça isso:

sudo rename -n 's/\.list$/.list.disable/g' /etc/apt/sources.list.d/*.list
sudo apt-get update
sudo apt-get -f remove oracle-java7-installer
sudo apt-get autoremove
sudo apt-get -f install
sudo apt-get install indicator-power

A primeira linha desativa qualquer repositório que não seja o oficial, o segundo atualiza a lista de pacotes, o quarto tenta reparar qualquer erro, o último instala o pacote.

    

Answer 2

Para instalar o oracle java SDK 7, basta procurar por ele no centro de software e instalá-lo. Se você precisar fazer o download de outros softwares no futuro, verifique o centro de software e eles têm muitas opções.
