I've tried using the repository of ubuntu 18.04 for an older version and failed, and now I've tried building 8.7 (the latest version) from source as seems to be the advised way. Also failed. As a completely new user I'm in no position to deal with this problem:

Error building Sage.

The following package(s) may have failed to build (not necessarily
during this run of 'make all-build'):

The build directory may contain configuration files and other potentially
helpful information. WARNING: if you now run 'make' again, the build
directory will, by default, be deleted. Set the environment variable
SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.

Makefile:31: recipe for target 'all-build' failed
make[1]: *** [all-build] Error 1
make[1]: Leaving directory '/home/robert/Sage/sage-8.7'
Makefile:16: recipe for target 'build' failed
make: *** [build] Error 2

Especially as a new user following install instructions for 8.7 exactly and getting nowhere, I am in no position to hack this install process: whether through Ubuntu (18.04) package installer or via 'make' (ie repository or source), every time I get errors - it's clear something is flawed with the instructions and/or the install process, but the long timescales and huge log files also mean I can't experiment or tweak things myself. I really am just lost on this one. Here's part of the log:
