[R-sig-Debian] undefined symbol: sgemv_thread_n (solved (?))

[Göran Broström]

Hi,

I removed openblas:

goran at M6800:~$ sudo dpkg --purge libopenblas-dev

and

goran at M6800:~$ sudo dpkg --purge libopenblas-base

which left me with

goran at M6800:~$ dpkg -l | grep blas
pi  libblas-dev:amd64 3.7.1-3ubuntu2  amd64        Basic Linear Algebra 
Subroutines 3, static library
ii  libblas3:amd64  3.7.1-3ubuntu2 amd64        Basic Linear Algebra 
Reference implementations, shared library

And now everything just works.
