That's fine. That's a relative link - relative to the location of the link.

This would create an absolute link.

Yes.

@Christophe, Bitjuggler - could you do the following (in that order):
get me the output of:
ls -l /etc/alternatives/openblas-default*
then try the following:
for i in openblas-default libblas.so.3 libcblas.so.3 liblapack.so.3
liblapacke.so.3; do
update-alternatives  --remove-all $i
done
Then force-install the script again?
