undefined symbol: sgemv_thread_n
Dirk, thanks for your help. At work I have (ubuntu 16.04): ii libblas-common 3.6.0-2ubuntu2 amd64 Dependency package for all BLAS implementations ii libblas-dev 3.6.0-2ubuntu2 amd64 Basic Linear Algebra Subroutines 3, static library ii libblas3 3.6.0-2ubuntu2 amd64 Basic Linear Algebra Reference implementations, shared library and everything works before and after upgrading (/usr/bin/R). However, at home (ubuntu 17.10): goran at M6800:~$ dpkg -l | grep blas ii 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 ii libopenblas-base:amd64 0.2.20+ds-4 amd64 Optimized BLAS (linear algebra) library (shared library) and it worked before upgrade but not after. Seems to be missing 'libblas-common'. So I try to install: goran at M6800:~$ sudo apt install libblas-common [sudo] password for goran: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package libblas-common So there is no such package in 17.10, but I have it in 16.04. What can be the replacement? Maybe I should downgrade to R-3.4.2, which works, but it doesn't feel right. G?ran

Both are 17.04, but that doesn't matter as they both have been updated regularly over the years. You must have gotten out of whack between what compiled R, and what runs it. Did you by chance compile R 3.4.3 locally?
Yes, first I installed R-3.4.3 from source and it started OK, but when I tried
library(eha)
I got the error above. So I installed by apt, and then I got the above. This is what I always have done, installing both from source and the ubuntu versions via 'apt upgrade', and it has always worked without problems. What has changed now? And how can I get out of this? G?ran
