[Bug 798478] Re: Partial upgrade spins indefinitely in “Preparing to upgrade” with multiarch

[Chris Halse Rogers]

Oh, this *wasn't* spinning indefinitely.  After about 15 minutes it halted with the following dialog error box:
“
Could not determine the upgrade

An unresolvable problem occurred while calculating the upgrade:
E:Unable to correct problems, you have held broken 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

This is most likely a temporary problem, please try again later.
”

** Summary changed:

- Partial upgrade spins indefinitely in “Preparing to upgrade” with multiarch
+ Partial upgrade spins for a long time in “Preparing to upgrade” before failing with multiarch

Title:
  Partial upgrade spins for a long time in “Preparing to upgrade” before
  failing with multiarch

Status in “update-manager” package in Ubuntu:
  New

Bug description:
  Binary package hint: update-manager

  I've enabled i386 as a foreign architecture on my amd64 box by adding
  “foreign-architecture i386” to /etc/dpkg/dpkg.conf and
  APT::Architectures { "amd64"; "i386"; }; in /etc/apt/apt.conf.d/99multiarch.

  I tried to upgrade using update-manager this morning (apt-get dist-
  upgrade works fine), and the partial update is just sitting at
  “Preparing to upgrade” with the progress bar flitting back and forth.
