The bug as it was originally reported by hanx9999 was about a malformed entry in a sources.list file this may have been created by add-apt-repository so I am moving the bug to the software-properties package which provides add-apt-repository.
The other issue adde by Paulo sounds like an incorretly formatted file for the medibuntu paa and that file should be deleted or fixed to be properly formatted.
