Невозможно установить / удалить любое приложение / пакет в UBUNTU 12.04 LTS, ошибка: JAVA_HOME

Это ошибка в «Окне сбоя операции пакета»:

Это информация о Java в моем Ubuntu. Я не уверен, что все они установлены правильно.

update-java-alternatives -l 
java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64
java-1.7.0-openjdk-amd64 1051 /usr/lib/jvm/java-1.7.0-openjdk-amd64

java -version
java version "1.6.0_30"
OpenJDK Runtime Environment (IcedTea6 1.13.1) (6b30-1.13.1-1ubuntu2~0.12.04.3)
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

echo $JAVA_HOME
/usr/lib/jvm/java-7-openjdk-amd64

Это следующее копирование и вставка из терминала, если я пытаюсь обновить:

Вывод nano /etc/environment:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"

JAVA_HOME = ":usr/lib/jvm/java-7-openjdk-amd64/bin"
