[Bug 871083] Re: package libpam-modules 1.1.3-2ubuntu1 failed to install/upgrade: ErrorMessage: './usr/share/man/man8/pam_shells.8.gz' is different from the same file on the system

[SwaJime]

I've been using aptitude for years without a problem, and the system upgrade
was not done with aptitude.
The upgrade was started from a dialog that kept popping up asking me to
upgrade the system.
That upgrade stopped and supposedly ran a "recovery", although I did not see
anything further happen.
I ran aptitude because that's what I've always used in the past.

I've reinstalled gnome-panel and upuntu-desktop and fglrx.  I don't know
what else might be broken, or even how to tell, except that everything
related to the wine has become inoperative.

I've opened a bug report for that at

Title:
  package libpam-modules 1.1.3-2ubuntu1 failed to install/upgrade:
  ErrorMessage: './usr/share/man/man8/pam_shells.8.gz' is different from
  the same file on the system

Status in “pam” package in Ubuntu:

Status in “pam” source package in Oneiric:
  Fix Committed

Bug description:
  SRU justification:
  libpam-modules is not multiarch-coinstallable because of unexplained misgeneration of compressed manpages on the buildds in a previous run.  This makes it impossible to use pam authentication for foreign-arch software due to the uninstallable modules, and also causes unpleasant upgrade issues.

  Test case:
  1) on amd64, enable armel in addition to i386 as a foreign architecture by running:
    echo 'foreign-architecture armel' >> /etc/dpkg/dpkg.cfg.d/multiarch-armel
    echo 'deb [arch=armel] http://ports.ubuntu.com/ubuntu-ports/ oneiric main' >> /etc/apt/sources.list
    apt-get update
  2) try to install libpam-modules for the other two architectures by running 'apt-get install libpam-modules:i386 libpam-modules:armel'
  3) confirm that both packages fail to install.
  4) enable oneiric-proposed (including for armel above).
  5) try to install libpam-modules for all three architectures by running 'apt-get install libpam-modules libpam-modules:i386 libpam-modules:armel'
  6) confirm that the packages install successfully.
