While this will work in most cases, the files in /var/lib/apt/lists/ are not
supposed to be used by other programs directly as discussed in #752702. Instead
the "apt-get files" command should be used to retrieve the exact location of
files in /var/lib/apt/lists/.

But using cat here is also not necessary because what you want is already done
by the command "apt-cache dumpavail".

Also, edos-debcheck doesn't exist anymore. Edos got replaced by dose, so now
you should use dose-debcheck.

In summary, the following should work:

apt-cache dumpavail | dose-debcheck -v -f -e sbuild-build-depends-yourpackage-dummy

Together with --build-deps-failed-commands you can create a hook which does
exactly what this bug requests. Would this be sufficient to fix this bug?

Thanks!

cheers, josch
