[Bug 767634] Re: dpkg regression --force-depends

[aplccorp]

Hello.

I had exactly the same problem that is described in this report.
After installing the dpkg package having the "proposed" deposit activated, everything worked perfectly, and I was able to install my Canon MP550 on my Ubuntu 11.04 AMD64

Many thanks!
APLC

Title:
  dpkg regression --force-depends

Status in “dpkg” package in Ubuntu:
  Fix Released
Status in “dpkg” source package in Natty:
  Fix Committed

Bug description:
  SRU justification:
  Regression in dpkg introduced by multiarch.  It is not impossible to force the installation of foreign-arch packages in natty if their dependencies are not installed.

  TEST CASE:
  1. Download http://people.canonical.com/~vorlon/force-arch-does-not-work_1.0_amd64.deb or http://people.canonical.com/~vorlon/force-arch-does-not-work_1.0_i386.deb (whichever one does *not* match the arch being tested on)
  2. Try to install the package with 'dpkg -i'.  Verify that it fails.
  3. Try to install the package with 'dpkg --force-architecture -i'. Verify that it fails.
  4. Try to install the package with 'dpkg --force-architecture --force-depends -i'.  Verify that it fails.
  5. Upgrade to dpkg 1.16.0~ubuntu7.1.
  6. Try to install the package with 'dpkg -i'.  Verify that it fails.
  7. Try to install the package with 'dpkg --force-architecture -i'. Verify that it fails.
  8. Try to install the package with 'dpkg --force-architecture --force-depends -i'.  Verify that it succeeds.
  9. remove the package with 'dpkg --purge force-arch-does-not-work:i386' (or :amd64).

  Binary package hint: dpkg

  I want to install a printer driver which is made with i386
  architecture on a amd64 system.

  With sudo dpkg -i --force-architecture rebuilt_common.deb, I obtain
  the following result:

  dpkg : avertissement : problème contourné par utilisation de --force :
   l'architecture du paquet (i386) ne correspond pas à celle du système (amd64)
  (Lecture de la base de données... 94096 fichiers et répertoires déjà installés.)
  Préparation du remplacement de cnijfilter-common:i386 2.90-1 (en utilisant rebuilt_common.deb) ...
  Dépaquetage de la mise à jour de cnijfilter-common:i386 ...
  dpkg : des problèmes de dépendances empêchent la configuration de cnijfilter-common:i386 :

   cnijfilter-common:i386 dépend de libcups2 (>= 1.2.1).
   cnijfilter-common:i386 dépend de libpopt0 (>= 1.7).
  dpkg : erreur de traitement de cnijfilter-common:i386 (--install) :
   problèmes de dépendances - laissé non configuré
  Des erreurs ont été rencontrées pendant l'exécution :

  Kubuntu 11.04

  This action worked perfectly with ubuntu 10.10 64 bits.
