this does work (replacing 1/4 by 0.25):
sage: taylor(0.25*x-x^2,x,0.2,3)
-1.0*(x - 0.2)^2 - 0.1501*x + 0.04002
Both ways work in Sage's Maxima:
$ sage --maxima

I have just updated my personal computer to fedora 26 and sagemath crashed.
The problem is that libgfortran.so.3 does not exist any more (version 4);
finally it worked forcing the reinstallation of openblas (sage -i -f
openblas). I do not know if there is an easiest work to solve the issue.

Rebuild from source?

I do not know exactly what you mean; I had built from source at the time of
installation; now it was enough to apply "sage -i -f openblas"

I got an error building Sage due to a package failing to be built. I have a
Lenovo Thinkpad 11e running Ubuntu Mate 16.04 LTS. Before beginning the
build, I checked that I had all the dependencies and suggested packages
installed beforehand. Then I pulled the code in through git and ran `make`.
My attempt to build Sage 7.6 resulted in an error. Before beginning, I
checked that I had all the required dependencies and suggested programs.
Then I got the code through git, set MAKE='make -j5 -j4' since I have four
physical cpu cores, and ran make. Make ran for about 45 min. and then

I have been attempting to build sage on arch recently (but not quite
succeeding so far). For what it's worth, I recently installed sagemath-git
(https://aur.archlinux.org/packages/sagemath-git/) and had no problem,
though. The sagemath-git AUR had a fully functioning sage within it
(although it
Similar issue in fedora 26; sage -i -f openblas solved it
