Answer 1

Tente criar um arquivo nessa pasta e execute o comando de desinstalação e, em seguida:

sudo mkdir -p /usr/java
sudo touch /usr/java/aa
sudo touch /usr/sbin/alternatives
sudo apt-get remove jdk1.8.0-40

EDITAR:

Tente isto:     echo "" | sudo tee /var/lib/dpkg/info/jdk1.8.0-40.postrm

    

Answer 2

  

/usr/sbin/alternatives: No such file or directory

  

     

Não há /usr/sbin/alternatives no Debian, Ubuntu, etc. Debian   clones. Em vez disso, há /usr/bin/update-alternatives .

     

Eu sugiro um link simbólico temporário para contornar os mal convertidos   Pacote RPM:

mkdir -p /usr/sbin
ln -sT -- /usr/bin/update-alternatives /usr/sbin/alternatives
