Eu tentei remover o jdk-6 usando:

sudo apt-get remove openjdk-6-jdk

Eu obtive o resultado como:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package 'openjdk-6-jdk' is not installed, so not removed
The following package was automatically installed and is no longer required:
  libc6-i386
Use 'apt-get autoremove' to remove it.
0 upgraded, 0 newly installed, 0 to remove and 2 not upgraded.

Desejo desinstalar openjdk-6-jdk , mas não devo remover openjdk-7-jdk , esperando solução.

apt-cache realiza uma variedade de operações no cache de pacotes do APT, ele não listará os pacotes instalados.

Para ver se um pacote openjdk está realmente instalado em seu sistema, basta digitar um terminal:

dpkg -l | grep openjdk
