[debhelper-devel] Bug#811491: debhelper: dh_installdocs --link-doc silently breaks package binNMUability

[Scott Kitterman]

Package: debhelper
Version: 9.20160115
Severity: important
Tags: patch

As predicted in the discussion in #747141, the current implementation for
the link-doc option, in compat +< 9, only causes warnings that no one notices
and results in warnings in build logs that no one will read and broken
packages as described in #811433.

As discussed on IRC, I think that the current behavior is just broken and
needn't wait for a compat bump.  With the attached patch broken packages will
FTBFS when the arch all packages are built.  I think this is a reasonable way
to do it since it is the arch all package with the wrong depends.

I did test this and it failed in the arch all -> any case and does not fail
for arch any -> arch any.
