[dist-upgrade] Maverick->Natty upgrade stumbles on monodoc

[Marcus Comstedt]

During the upgrade from Maverick to Natty, an error occured in a trigger for the monodoc-base package:

[...]
Processing triggers for monodoc-base ...
generating monodoc search index...

** (/usr/lib/monodoc/browser.exe:32441): WARNING **: The following assembly referenced from /usr/lib/monodoc/browser.exe could not be loaded:
     Assembly: gtk-sharp (assemblyref_index=2)

The assembly was not found in the Global Assembly Cache, a path listed in the MONO_PATH environment variable, or in the location of the executing assembly (/usr/lib/monodoc/).

dpkg: error processing monodoc-base (--unpack):
 subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
 monodoc-base
dpkg: libindicator1: dependency problems, but removing anyway as you requested:
 libappindicator1 depends on libindicator1; however:
  Package libindicator1 is to be removed.

The monodoc-base package was later replaced, without any problems at all:

[...]
Unpacking replacement mono-mcs ...
Preparing to replace monodoc-base 2.6.7-3ubuntu1 (using .../monodoc-base_2.6.7-5ubuntu3_all.deb) ...
Unpacking replacement monodoc-base ...
Preparing to replace mousetweaks 2.32.0-0ubuntu1 (using .../mousetweaks_3.0.0-0ubuntu2_powerpc.deb) ...
[...]
Setting up mono-mcs (2.6.7-5ubuntu3) ...
Setting up monodoc-base (2.6.7-5ubuntu3) ...
Setting up nautilus-share (0.7.2-14ubuntu1) ...
[...]

The end result was that the dist-upgrade claimed that one error had
occured, and refused to run the "cleanup" and "reboot" steps.

Maybe running triggers for packages that are going to be replaced
anyway should be avoided?

Hello
Are you encountering again this problem with the latest release Oneiric Ocelot ?
Thanks
