Comment (by chapoton):
Failures in
src/sage/schemes/hyperelliptic_curves/hyperelliptic_padic_field.py seem to
be just about slight changes in precision (either gain or loss by one).
Maybe one can just correct the result of the doctests.
Failures in src/sage/rings/multi_power_series_ring_element.py are more
serious: they come from trying to build a Laurent series ring in several
variables, that we currently do not have !
