[Bug 1240707] Re: Migration failure to kubuntu 12.10 64bits (hostname, libpam-modules)

[Christophe Chisogne]

Here's the bug report title automatically generated before the system
tried to "dpkg --configure -a" ( it didn't sent it ).

package libpam-modules 1.1.3-7ubuntu3 failed to install/upgrade:
ErrorMessage: problème de pré-dépendance - libpam-modules:amd64 non
installé

Installing "libpam-modules:amd64" will most probably fix the issue for
me

Title:
  Migration failure to kubuntu 12.10 64bits (hostname, libpam-modules)

Status in “ubuntu-release-upgrader” package in Ubuntu:
  New

Bug description:
  The migration from 12.04 LTS to 12.10 (64bits) failed on my box because of 2 packages dependency failures:
  libpam-modules and hostname.

  I recover it in a shell after reboot (no GUI was available btw) by 
  - using repeated calls to aptitude -f install ( the process stopped several times because of "too many errors" messages)
  - manually installing some packages
  - manually removing some packages with failed dependencies
  - manually installing the 2 above packages (aptitude install libpam-modules hostname)

  I'm upgrading from 12.10 to 13.04 right now, and the same failure
  seems to happen again during the package installation process (after
  the download step). So I think this could affect users migrating from
  12.04 TLS to the next TLS release.

  FWIW, the original distribution installed on this box was 11.04
  (Natty), and I used some custom sources.list at some point (medibuntu
  and another one to install the Zend PHP framework)

  I did not investigate a lot, but this could be related to mixed
  dependencies between 32bit and 64bit versions of some packages.
