  • Can you make system updates? What happensif you try to install the same package via a console with the command sudo apt-get install packagename? – Alvar Nov 03 '11 at 15:55
  • when i try to install by update manager it again says:"Requires installation of untrusted packages

    The action would require the installation of packages from not authenticated sources."
