Hi Matthieu, hi Adam,

The set of packages you uploaded contains uninstallable udebs, as they
depend on sgml-base, which doesn't exist in the installer context
(there's no udeb for it. Current dependencies are as follows:

    $ dpkg --info libnl-3-200-udeb_3.7.0-0.1_amd64.udeb|grep Depends
     Depends: sgml-base (>= 1.28), libc6-udeb (>= 2.34)

    $ dpkg --info libnl-genl-3-200-udeb_3.4.0-1+b1_amd64.udeb|grep Depends
     Depends: libnl-3-200-udeb (= 3.4.0-1+b1), libc6-udeb (>= 2.28)

This leads to the following build failure for the daily builds of the
installer:

    The following packages have unmet dependencies:
     libnl-3-200-udeb : Depends: sgml-base (>= 1.28) but it is not installable
     libnl-genl-3-200-udeb : Depends: sgml-base (>= 1.28) but it is not installable
    E: Unable to correct problems, you have held broken packages.

(Note that I'm filing this bug report against only one of those udebs.)

This is not your fault, that's debhelper's #1015263:
  https://bugs.debian.org/1015263

but I thought I'd loop you in so that you know about this issue, and
about my current plan: the installer team (X-D-Cc'd) doesn't require an
immediate fix, but since I'm not sure when the debhelper bug is getting
fixed (and packages binNMU'd), I thought I'd prepare a workaround to
make sure this source package isn't a blocker when we plan for a Debian
Installer release.

I'll upload shortly, source debdiff attached. Please let me know if you
have any comments or questions.


In passing, thanks for your work on this package!


Cheers,
