    - A bug in C(apt-add-repository) always adds C(deb) and C(deb-src) types for repositories (see the issue on Launchpad U(https://bugs.launchpad.net/ubuntu/+source/software-properties/+bug/987264)), if a repo doesn't have source information (eg MongoDB repo from 10gen) the system will fail while updating repositories.
