I took a look at this and the problem is simply that the load path
contains Octave's version number. No soname incompatibility. And
unless something is changed, this will continue to be the case between
different upstream versions of octave and liboctaveX.
The octave package provides the directories, and liboctinterp.so.1 has
a compiled-in set of paths with its version number that it attempts to
load. You can see these paths with:
$ strings /usr/lib/x86_64-linux-gnu/liboctinterp.so.1 | grep /3.6../
If I print the default path from a working 3.6.3:
$ octave -qf --eval "disp(path)"
then downgrade liboctave1/sid and set that full string to be the path
in the interpreter:
$ octave -qf
octave:1> ls
error: feval: function `unimplemented' not found
octave:1> path (full_path_here);
octave:2> ls
no more error.
