[R-sig-Debian] undefined symbol: sgemv_thread_n

[Göran Broström]

Hello,

the following is a part of a question asked on R-help. I realized that 
it is better suited for asking here. Apologies for the cross-posting!

I'm on Ubuntu artful, and upgraded with 'apt'. Then

----------------------------------------------------------------
goran at M6800:~/src/R-3.4.3$ /usr/bin/R
/usr/lib/R/bin/exec/R: symbol lookup error: 
/usr/lib/x86_64-linux-gnu/libblas.so.3: undefined symbol: sgemv_thread_n
----------------------------------------------------------------

Never seen this before. What can I do?
