SAGE mathematics from binary because there was no package for it in
synaptic. From reading on the web I learned that
SAGE brings its own
python libraries rather than using the ones Ubuntu /
synaptic has already installed.
I'm getting low on hard disk space -- what can/should I delete? Or how should I rejigger my libraries / system to avoid duplicating 𝓞(gigabytes) worth of libraries?
BTW, I'm having a similar problem with
texlive-full -- I first downloaded the package in
synaptic, then realised it was outdated, then downloaded the
iso -- and now I think I have three or four copies of
LaTeX on my drive.
