I think this is clearly related to a recent library packaging change in Debian unstable where the Q16 suffix was added to the library. Your build of Octave is now outdated, you probably compiled it against libgraphicsmagick++11 and just need to rebuild and reinstall Octave now with libgraphicsmagick++-q16-11.

The error message is reasonably clear. Your system is missing a library file libGraphicsMagick++-Q16.so. You need to figure out which package in Debian Unstable supplies this library. I think something like this should give you an idea.

Error Message:

error: _imwrite_: /usr/lib/x86_64-linux-gnu/octave/4.0.0/oct/x86_64-pc-linux-gnu/__magick_read__.oct: failed to load: libGraphicsMagick++-Q16.so.11: Kann die Shared-Object-Datei nicht öffnen: Datei oder Verzeichnis nicht gefunden

It happens since a Debian Unstable Update a week ago.
It might be also a problem with Graphicsmagick itself,
anyway I want to let you know...

The code to reproduce the error:

clear all,
more off
Bild=round(rand(5,1)*20)
imwrite(uint16(Bild),'YouSee.jpeg','Quality',100)

For "Bild" take any Matrix, doesn't matter if png- or jpeg-file...

Greetings
