Comment 19 for bug 2040059

I can confirm that the sagemath package in mantic-proposed has fixed the bug for me.

Test done according to the testplan:

$ sage
┌────────────────────────────────────────────────────────────────────┐
│ SageMath version 9.5, Release Date: 2022-01-30 │
│ Using Python 3.11.6. Type "help()" for help. │
└────────────────────────────────────────────────────────────────────┘
sage: 2 + 2
4
sage: factor(-2007)
-1 * 3^2 * 223
sage: A = matrix(4,4, range(16)); A
[ 0 1 2 3]
[ 4 5 6 7]
[ 8 9 10 11]
[12 13 14 15]
sage: factor(A.charpoly())
x^2 * (x^2 - 30*x - 80)

Test result: the errors with sagemath has been fixed.
