This is a list of packages in Ubuntu, which never appeared in *any* Debian release, with a minimum number of installations in Ubuntu according to popcon. See below for the current threshold.

Some of them have been blacklisted, either because are Ubuntu-specific, or because Debian has an alternative for various reasons (think of the firefox-iceweasel case).

Total sources with popcon >= 200: 895
