All reports of missing-debconf-dependency-for-preinst for the archive. The extended description of this tag is:

Packages using debconf in their preinst script must pre-depend on debconf, with appropriate discussion on debian-devel. Since debconf is almost always already installed, this is normally better than depending on it and falling back to a different configuration system.

Severity: normal, Certainty: possible

Check: debconf, Type: binary, udeb, source
