Can't create an i386 ISO, but amd64 works fine

[Daniel Ellison <daniel@syrinx.net>]

Hi all,

I've successfully created amd64 ISOs several times. When I want to do 
the same for i386, I change "--architectures" to i386 and do

lb clean --purge; lb config; lb build

Eventually it says this:

P: Begin executing preseed...
P: Begin executing local preseeds...
P: Begin queueing installation of package lists (install pass)...
P: Begin queueing installation of local package lists (install pass)...
P: Begin queueing installation of local packages...
P: Begin installing packages (install pass)...
Reading package lists...
Building dependency tree...
Reading state information...
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gdm : Depends: libglade2-0 (>= 1:2.6.1) but it is not going to be 
installed
       Depends: libgnomecanvas2-0 (>= 2.11.1) but it is not going to be 
installed
       Depends: libgtk2.0-0 (>= 2.18.0) but it is not going to be installed
       Depends: libpango1.0-0 (>= 1.14.0) but it is not going to be 
installed
       Depends: librsvg2-2 (>= 2.26.0) but it is not going to be installed
       Depends: gksu (>= 1.0.7) but it is not going to be installed
       Depends: librsvg2-common but it is not going to be installed
       Recommends: zenity but it is not going to be installed

The "gdm" part is just an example. it says similar things about every 
package I have in my chroot_local-packagelists/syrinx.list

The ISO is created with no errors when I set "--architectures" to amd64 
and do the same set of commands.

Is there anything I'm doing obviously wrong? I can provide my 
auto/config, syrinx.list etc. if needed.

Thanks,
Daniel
