Na verdade, eu estava tentando instalar o Java (para o Hadoop) no Ubuntu 16.04. Mas sempre que eu tento executar o sudo apt-get update eu sempre recebo o erro de:

W: You may want to run apt-get update to correct these problems
E: The package cache file is corrupted
e depois disso sempre que eu executo o comando:
sudo apt-get install default-jdk
sempre recebo um erro de:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package default-jdk
Deve haver algumas linhas antes de E: Unable to parse package file mostrar erros como este:
E: Unable to parse package file /var/lib/apt/lists/…
Você precisa
sudo rm -i /var/lib/apt/lists/*
sudo apt update
Não não esqueça o asterisco * no primeiro comando!
