Eu quero mudar o Java 8 para o Java 7. Eu planejei remover o Java 8 First. Eu corro o seguinte cmd
sudo apt-get purge oracle-java8-installer
Eu tenho o seguinte erro
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-signed-image-3.16.0-34-generic : Depends: linux-image-3.16.0-34-generic (= 3.16.0-34.47) but 3.16.0-34.45 is to be installed
oracle-java8-set-default : Depends: oracle-java8-installer but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
