The Ubuntu packaging is buggy, iirc. I remember running into this
question in the #octave channel. The problem is that the packaging has
directories architecture-specific names in it that conflict with the
architecture that you're running. If you do

     dpkg -L octave-image

and

     uname -m

I think you should see that octave-image is installing to directories
with 64-bit architecture names in it and your system is 32-bit, or
vice versa; I forget the exact details.

The problem is that nobody is looking at Ubuntu's Octave packaging.
Ubuntu doesn't have dedicated per-package maintainers like Debian
does. Colin Watson fixed a packaging bug in Ubuntu last time I asked,
and perhaps he will do it again, or perhaps you can submit a fix to
Ubuntu's packaging yourself.
