The blas package provides a compatibility symlink for libblas.so.3gf, so
octave needs not to be recompiled to accomodate this transition. On my
system the upgrade went smoothly.

Can you please send the result of:

 sudo update-alternatives --display libblas.so.3 

On my system this command gives:

libblas.so.3 - auto mode
  link currently points to /usr/lib/openblas-base/libopenblas.so.0
/usr/lib/atlas-base/atlas/libblas.so.3 - priority 35
  slave libatlas.so.3: /usr/lib/atlas-base/libatlas.so.3
  slave libblas.so.3gf: /usr/lib/atlas-base/libblas.so.3
  slave libcblas.so.3: /usr/lib/atlas-base/libcblas.so.3
  slave libf77blas.so.3: /usr/lib/atlas-base/libf77blas.so.3
  slave liblapack_atlas.so.3: /usr/lib/atlas-base/liblapack_atlas.so.3
/usr/lib/libblas/libblas.so.3 - priority 10
  slave libblas.so.3gf: /usr/lib/libblas/libblas.so.3
/usr/lib/openblas-base/libopenblas.so.0 - priority 40
  slave libblas.so.3gf: /usr/lib/openblas-base/libopenblas.so.0
Current 'best' version is '/usr/lib/openblas-base/libopenblas.so.0'.

As you can see, there is a slave alternative providing libblas.so.3gf.
