Hello,
Here is the report of a crash that happened while trying to lunch sage:
-Operating system: Ubuntu 20.04 beta, upgraded from 19.10.
-Sage (8.9) was build from the source under Ubuntu 19.10 and by following
the instructions in this page
http://doc.sagemath.org/html/en/installation/source.html.
No special flags were used except to change the build directory.
-The crash happened by lunching sage (with no arguments) from the terminal,
it is worth noting that the crash happened just after I upgraded my Ubuntu
from
19.10 to 20.10.
Best regards,
Soufiane Lakhlifi.

2 Ring `\ZZ` of Integers
3
4 The :class:`IntegerRing_class` represents the ring `\ZZ` of (arbitrary
5 precision) integers. Each integer is an instance of :class:`Integer`,
6 which is defined in a Pyrex extension module that wraps GMP integers
7 (the ``mpz_t`` type in GMP).

15 sage: Z.is_field()
16 False

18 There is a unique instance of the :class:`integer
ring<IntegerRing_class>`.
19 To create an :class:`Integer`, coerce either a Python int, long, or a
string. Various
20 other types will also coerce to the integers, when it makes sense.
