  • 772

I had installed OpenJDK 7 Runtime (openjdk-7-jre) and when it was installed, it also accompany with lot of package depends, but when i wanted to remove. it just removed openjdk-7-jre size 800 kb, and not removed all OpenJDK 7 Runtime depends. Actually, it become unnecessary packages.

How should I do to fix it?

  1. If the other packages were installed only as dependencies of openjdk-7-jre and you have removed openjdk-7-jre, you should be able to remove those now-unnecessary packages with:

    sudo apt-get autoremove

    If you want to remove their systemwide configuration files too, run this instead:

    sudo apt-get --purge autoremove

  2. I also suspect that there must be a pile of old applications that I tried but discarded. I have also uploaded many packages that simply did not work on Ubuntu, for example Debian software. You have to remove those downloads manually.
