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@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@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.

In other words, I tend to use standard blas or openblas or atlas
(but seemingly less often). 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?
