  1. program dies with stacktrace, though it's not code error. Applicable
  environment errors (i.e. user-level errors like wrong data or missing
  files) must not show stack traces!

  2. error message doesn't give user a clue about how to fix the problem.
  Yes, it tells him about missing 'distribution template', but user
  doesn't know what is it and where to find it to fix it. Giving him
  template location ' /usr/share/python-apt/templates' helps to locate
  wrong package:
