AIUI this isn't really surprising, there is no problem once all packages
are at their newest versions, we just need to add metadata so that dpkg
unpacks them in the right order.

Title:
  libc6-dev:amd64 overwrites files from libc6:i386 and aborts update
  when upgrading to mantic

Status in glibc package in Ubuntu:
  Triaged

Bug description:
  This is a bug affecting mantic, apport selected lunar instead of
  mantic because the bug happens in the middle of the upgrade from lunar
  to mantic.

  I tried to update from lunar to mantic, dpkg aborted with this error:

  ```
  Dépaquetage de libc6-dev-i386 (2.38-1ubuntu6) sur (2.37-0ubuntu2.1) ...
  dpkg: erreur de traitement de l'archive /var/cache/apt/archives/libc6-dev-i386_2.38-1ubuntu6_amd64.deb (--unpack) :
   tentative de remplacement de « /usr/include/finclude/math-vector-fortran.h », qui appartient aussi au paquet libc6-dev:amd64 2.37-0ubuntu2.1
  ```

  The message is in French, but the meaning is that dpkg aborts because
  installing libc6-dev:i386 tries to overwrite files from
  libc6-dev:amd64.
