    open a terminal (Ctrl+Alt+T) and run:

    sudo apt-add-repository --remove ppa:upubuntu-com/office

    or with help of ppa-purge has to be installed: sudo apt-get install ppa-purge

    sudo ppa-purge ppa:upubuntu-com/office

sudo apt-get update && sudo apt-get upgrade

sudo apt-get autoremove

    The reason you're getting this error is because given PPA has ended on 12.10 Quantal support, so you need to disable/remove it.
