Hi, today I wanted to remove "OpenJDK Java 7 Runtime" in the Software Center.

But once I remove "OpenJDK Java 7 Runtime" it would automatically also install "OpenJDK Java 6 Runtime" and "IcedTea Java Web Start".

When I remove "OpenJDK Java 6 Runtime" (and "IcedTea Java Web Start") there will be automatically "OpenJDK Java 7 Runtime" installed.

What can I do?

Try running these commands in the terminal:


sudo apt-get update
apt-cache search java | awk '{print($1)}' | grep -E -e '^(ia32-)?(sun|oracle)-java' -e '^openjdk-' -e '^icedtea' -e '^(default|gcj)-j(re|dk)' -e '^gcj-(.*)-j(re|dk)' -e 'java-common' | xargs sudo apt-get -y remove
sudo apt-get -y autoremove Purge config files:

dpkg -l | grep ^rc | awk '{print($2)}' | xargs sudo apt-get -y purge Remove Java config and cache directory:

sudo bash -c 'ls -d /home/*/.java' | xargs sudo rm -rf Remove manually installed JVMs:

sudo rm -rf /usr/lib/jvm/* Remove Java entries, if there is still any, from the alternatives:
