[Bug 850264] Re: given a foreign architecture of i386 on amd64 machine, and an outdated libc, apt tries to remove libc-bin

This issue still affects upgrades from oneiric to precise (see duplicate
bug #940571) because the upgrader uses the oneiric version of apt.  So
we may need to backport this.

** Also affects: apt (Ubuntu Oneiric)
   Importance: Undecided
       Status: New

** Changed in: apt (Ubuntu Oneiric)
   Importance: Undecided => High

** Changed in: apt (Ubuntu Oneiric)
       Status: New => Triaged

Title:
  given a foreign architecture of i386 on amd64 machine, and an outdated
  libc, apt tries to remove libc-bin

Status in “apt” package in Ubuntu:
  Fix Released
Status in “apt” source package in Oneiric:
  Triaged
Status in “apt” source package in Precise:
  Fix Released

Bug description:
  This reproducer was verified to work in the live system of current
  precise-dailies. It doesn't work on an installed system where
  libc6:i386 is already installed!

  1. Drop libc6-dev:
     sudo dpkg -P libc6-dev

  2. Downgrade to a previous libc:

    wget https://launchpad.net/ubuntu/+source/eglibc/2.13-20ubuntu9/+build/2979954/+files/libc-bin_2.13-20ubuntu9_amd64.deb https://launchpad.net/ubuntu/+source/eglibc/2.13-20ubuntu9/+build/2979954/+files/libc6_2.13-20ubuntu9_amd64.deb
    sudo dpkg -i libc*.bin

  3. Ensure apt is consistent:

      sudo apt-get install -f

    should not complain about anything.

  4. Install i386 package:

    sudo apt-get install cpp:i386

    This will propose to remove libc-bin and install the newer version
  of libc-bin:i386 instead.

  It seems that apt prefers install the foreign arch libc6-bin:i386 over
  upgrading the native arch libc6-bin to the current version?

  WORKAROUND
  If you get this bug with Precise Alpha1 you can workaround by:
  * Keeping 'install 3rd party software' _unchecked_ in the Prepare step of Ubiquity
  or
  * Disconnecting the system from the network before starting the installation

  Original bug report:

  Today I added i386 as a foreign architecture and then tried to install
  something with apt, but was presented with a very bad plan:

  To fix this, on slangasek's advice, I did

  $ sudo apt-get install skype:i386 libc-bin

  This upgraded libc-bin instead of removing it.
