    That's correct and the reason is: No packages for Trusty in this PPA. Remove the PPA. Open a terminal and run:

    find /etc/apt -type f -name '*.list' -exec sudo sed -i '/gwibber-daily/d' {} \;
sudo apt-get update

    The package gwibber is in the Trusty Universe repositories. To enable the repository:

    sudo apt-add-repository universe
sudo apt-get update

  2. Open the 'Software & Updates' program, click 'Other Software' - scroll down the list until you see an entry that looks something like http://ppa.launchpad.net/ppa:gwibber-daily/ppa and uncheck it's seleciton box. This PPA does not support Ubuntu Trusty.
