Thanks Dirk.  I did an upgrade and the NOTE went away, so I guess that 
all is well.

I'm never sure about upgrading with "sudo apt whatever", so I was a bit 
apprehensive.  For the record I did:

     sudo apt update
     sudo apt upgrade r.base

The latter took quite a while; 15 or 20 minutes.  There's probably 
something simpler that I could have done, but when you don't know, you 
don't know.

There was no indication that I am now getting version 3.6.0-2; any 
enquires about the version that I can seem to make indicate version 
3.6.0; no "-2" in sight.  However, as I said above, it seems to have worked.

cheers,

Rolf
