Maybe. Maybe not. Did you check packages.ubuntu.com (or another source) to
see if it still exists?  Per
https://packages.ubuntu.com/search?keywords=libblas-common it is only listed
for xenial (16.04) and zesty (17.04), not your 17.10.

| 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

No that would not be right.

To recap: you have an issue on 17.10 only, and the R is self-built or the one
installable as binary via CRAN?

Dirk
