Apparently libsemigroups (ticket 27396) is not on the mirrors.

FWIW, on Debian testing running on core i7 + 16 GB RAM, a Python3 upgrade from 8.9beta4 gives me 3 failures, all permanent:

----------------------------------------------------------------------

sage -t --long --warn-long 158.3 src/sage/graphs/strongly_regular_db.pyx # 4 doctests failed

sage -t --long --warn-long 158.3 src/sage/algebras/quantum_groups/quantum_group_gap.py # Killed due to segmentation fault

sage -t --long --warn-long 158.3 src/sage/rings/polynomial/polynomial_rational_flint.pyx # 1 doctest failed

----------------------------------------------------------------------

Thr third one has already been reported , and I'm aware of a relevant ticket been worked on. OFAICT, the first two are novel.

On another machine (Debian testing, core i5 + 8 GB RAM), I get only the already-multi-reported FLINT error.

I'll try to rebuild Sage on the larger machine to see if the errors aren't accidental.

HTH,

A second attempt, on my first, "larger", machine, to rebuild Sage 9.9.beta6 using Python3 gave the same results as the first attempt, which was an upgrade from 6.9.beta4, IIRC. Same permanent ptest-python3 failures. This reproducibility points to possibly different components in the environment.
