Package: lintian Version: 1.23.25 Severity: wishlist When debconf is used in the preinst, there must be a pre-depends on debconf (>= 0.5) | debconf-2.0. Could you please add a check for that? You can also note that in this case, the no-debconf-config warning is wrong, and postinst-does-not-load-confmodule is as well (unless there is also a config script).
