I frankly don't understand Debian/Ubuntu packaging of SageMath. E.g. Sage 9.0 was never tested with Python 3.9, and their current version of cysignals.
Surely they are trying to backport our changes, but this is quite error-prone. Please use conda, or build from source, or use Linux distro with much more up to date Sage, e.g. archlinux or Gentoo.
