[Bug 1015329] Re: dpkg fails to run after update (error: file triggers record mentions illegal package name `libgtk2.0-0' (for interest in file `/usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/immodules'): ambiguous package name 'libgtk2.0-0' with more than one installed instance)

[Stephen Cradock]

This is confusing me - my quantal system has dpkg 1.16.4.3ubuntu1.
Updating works fine, but there is no sign of the ..ubuntu2 package yet.

Are we looking at the same package? - 1.16.3 or 1.16.4.3?

Title:
  dpkg fails to run after update (error: file triggers record mentions
  illegal package name `libgtk2.0-0' (for interest in file
  `/usr/lib/x86_64-linux-gnu/gtk-2.0/2.10.0/immodules'): ambiguous
  package name 'libgtk2.0-0' with more than one installed instance)

Status in “dpkg” package in Ubuntu:
  Fix Released

Bug description:
  dpkg 1.16.3ubuntu1 aborts with an error if any multiarch libraries are
  installed which declare triggers.  The error message looks like this:

  dpkg: error: file triggers record mentions illegal package name
  `libgtk2.0-0' (for interest in file `/usr/lib/x86_64-linux-
  gnu/gtk-2.0/2.10.0/immodules'): ambiguous package name 'libgtk2.0-0'
  with more than one installed instance

  This makes it impossible to install any further packages with the dpkg
  command until the triggers file is updated for the new syntax.

  To fix the triggers file, run the following command from a terminal:

  arch=$(dpkg --print-architecture | tail -n1); while true; do
  res=$(sudo dpkg --configure -a  2>&1 | sed -n -e"s/.*file triggers
  record mentions illegal package name \`\([^']*\)'.*/\1/p"); if [ -z
  "$res" ]; then break; fi; echo Fixing trigger for package $res; sudo
  sed -i -e"s/$res\$/$res:$arch/" /var/lib/dpkg/triggers/File; done

  This will correct the dpkg configuration and allow you to proceed with
  the upgrade.

  dpkg 1.16.3ubuntu2 will be released later today with a fix for this
  issue.  Users who have not yet upgraded to dpkg 1.16.3ubuntu1 in
  quantal are advised to wait for 1.16.3ubuntu2 before upgrading.
