This is because you're using aptitude, which has a different resolver and
handles uninstallable recommends differently than apt-get does.  apt itself
has no problem installing ia32-libs without installing libmysqlclient16.

Title:
  Natty->Oneiric Upgrade failed: An unresolvable problem occurred while
  calculating the upgrade

Status in “ia32-libs” package in Ubuntu:
  Invalid
Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  I got the following error message pop-up:

  ----------
  Could not calculate the upgrade

  An unresolvable problem occurred while calculating the upgrade:
  E:Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

   This can be caused by:
   * Upgrading to a pre-release version of Ubuntu
   * Running the current pre-release version of Ubuntu
   * Unofficial software packages not provided by Ubuntu

  If none of this applies, then please report this bug using the command 'ubuntu-bug update-manager' in a terminal.
