I don't want OpenJDK installed on my Ubuntu 13.04 system, but trying to uninstall the openjdk-7-jre yields the following message.

Do you want to continue [Y/n]?

What do I need to do so that no new packages, of which I need none, will be installed when removing openjdk-7 ?

Great question i was always wondering this

I found that you can use the following to remove the openjdk-7-jre on Ubuntu 13.04.

sudo apt-get autoremove openjdk-7-jre

Press 'y' and then press enter when prompted to confirm this change. This should also clean up all the additional dependency libraries that were installed with it

I also found you can use the following command to perform a additional cleanup

sudo apt-get purge openjdk*

If you use the following command

java -version

You should no longer see the openjdk-7-jre installed

I hope this helps :)
