Comment 3 for bug 992685

Well, I did install all oneiric updates that were present over the weekend before updating. Although I'm confused as the ...13.3 apt was reportedly published 4/25 and I did upgrades between 4/26 and 4/29. Even so looking at the logs, they both list apt ....13.2.

Anyway, from the apt ....13.3 changelog it does sound like the issue has been hopefully addressed:
" * Backport fixes from precise verison of apt, to fix multiarch upgrades
    from oneiric."

As my machines are already upgraded, I cannot "try the upgrade again". I guess we can just hope its fixed and no one else hits this.
