Ubuntu – Package manager doesn’t work anymore


I'm using ubuntu 10.10 and recently my package manager has stopped working because of some problems with dependencies or something. I can't upgrade, install or uninstall anything at all. This is a huge problem. I couldn't find a solution to this with google so I'm asking here for help.

This is what apt-get -f install outputs

LANG=en_US.UTF-8 sudo apt-get install -f

Best Answer

  • I'd just reinstall the package...

    sudo mv /var/lib/dpkg/info/openjdk-6-jre-headless.postinst /var/lib/dpkg/info/openjdk-6-jre-headless.postinst.bad
    sudo apt-get --reinstall install openjdk-6-jre-headless
