Since ubuntu 17.10 I have seen this sagemath and jupyter-notebook which
much simplifies a good installation of sagemath

Hi
I thought there were no binary tarballs for 18.04?

Hi Jan
I initially installed from the binary tarball. Successfully tried
sudo apt install tk tk-dev
sage -f python2
Ubuntu18.04 seems to be missing several development tools. So I
guess this will all be resolved when a version of sage for 18.04
is formally released.
Many thanks for your help.

Did you install from source? (versus from apt / software centre?)
http://doc.sagemath.org/html/en/installation/source.html#tcl-tk
So it looks like even if you just sudo apt install tk8.6 (and
mabye tk8.6-blt2.5??)
your ubuntu python might pick it up but not the sage python.
So you should sudo apt install tk8.6-dev (and mabye tkblt-dev??)
and then rebuild the sage python as per the instructions at
the link above.
tk packages in ubuntu 18.04:
https://packages.ubuntu.com/search?keywords=tk&searchon=names&suite=bionic§ion=all
Or perhaps there is someone else who can answer if one can
tell Sage not to try to use tk for
show(lines(... but to use another graphics toolkit.

Jan
