That applies to non-Debian repositories but not to PPAs that's
probably why Ubunical created "apt-add-repository" with which you can
add any repository including PPAs and VirtualBox to
"/etc/apt/sources.d/" along with its corresponding gpg key but limited
itself to "ppa-purge" rather than increasing the complexity of its
removal script with "apt-purge-repository" (which is what the OP wants
to do).
