Jan: Sorry, forgot to mention that I used the 16.04 tarball on 18.04. Vincent: Tried installing sagemath using your recipe. Works OK for my original problem. However, have now reverted for several reasons... (a) 8.1 not 8.3 (b) I usually add packages to the GAP pkg directory. I didnt find such a directory. sagemath structure looks very different. (c) Seems slower than 16.04 tarball solution.
