Follow-up Comment #4, bug #61834 (project octave):

I think in Ubuntu /usr/lib/x86_64-linux-gnu/libblas.so is a symlink to the
default blas library (i.e. the broken openblas, I presume).
You need to figure out the actual location of the reference blas 
(libblas3 or similar name). You may not have it installed. 
I would guess it would be

/usr/lib/x86_64-linux-gnu/blas/libblas.so.3

So try:



LD_PRELOAD=/usr/lib/x86_64-linux-gnu/blas/libblas.so octave



I assume you should also be able to switch the default using
"update-alternatives" mechanism.

Dmitri.
