Thanks for starting this thread.  I have the exact same problems on a fresh
install of Ubuntu 20.04.

ans = unknown or reference BLAS

Elapsed time is 0.00454998 seconds.
octave:4> tic; eig(rand(92)); toc
hangs forever

Has there been any resolution or fix ?

The problem is with ubuntu, not octave. Go file the bug report againt their openblas

library.

BTW the snap version of Octave under Ubuntu 20.04 seems to work fine.
