It's pretty likely that the lintian check is buggy in this case;
nevertheless, your depends: line is *also* buggy.
Depends: debconf (>= 0.5) | debconf-2.0, debconf (>= 1.3.22) | debconf-2.0
Reduces to
Depends: debconf (>= 1.3.22) | debconf-2.0
*but*, this in turn reduces to
Depends: debconf-2.0
because there are versions of debconf older than 1.3.22 which provide
debconf-2.0 (the Provides: was introduced in debconf 1.2.30), so they
satisfy the second branch of the dependency relationship when they
*shouldn't*.
If you depend on newer features than those guaranteed by the debconf-2.0
interface, you will need to depend on the providers of those features
explicitly, *without* an or on "debconf-2.0".
