Comment 13 for bug 1023964

matteo, if python-apport is installed, then python-launchpadlib should be as well as that is a strict dependency. Indeed the current version gives you an error message as you suggested:

   if ! python -c 'import apport' 2>/dev/null; then
        echo "You need to run 'sudo apt-get install python-apport' for apport-collect to work." >&2

So if you still get that error, then something else is wrong on your system. Please give me the output of

  python -c 'import apport'

Thanks!
