It turns out that the original author has also posted this problem in 
sage-devel , wher we 
should continue…

For now, it's still through trac, I believe, but in a few weeks it would 
but a through github issues. With the reproduction in maxima standalone, 
especially because the erroneously solved system is obtained by 
specialization from a system that is solved correctly, this can be reported 
"upstream" to maxima and I'm sure it will get due attention eventually.

Their bug reporting hasn't changed, I think:

[sage-support] Somethog in rotten is the state of Maxima...

2022-10-09 Thread Emmanuel Charpentier 
... and all is not fresh in Sympy's realm either.

Full details in [this ask.sagematjh.org 
question](https://ask.sagemath.org/question/64344/solving-a-system-of-linear-equations-with-complex-numbers-yields-false-solution/?answer=64363#post-id-64363).

TL;DR : a linear system, perfectly solved by Sage's default solver (i. e. 
Maxima's), gets a wrong answer when one of its variables is replaced by the 
`I` (*i*, imaginary unit) constant.

The problem can be reproduced in `maxima` used standalone. (see referenced 
post).

Furthermore, the same system (with *i*) seems to confuse `sympy` to no 
extend : `solve(Sys, IVars), algorithm="sympy")`doesn't return after more 
than 15 minutes, whereas the solution of the system with a variable instead 
of *i* is solved in a matter of milliseconds...

Giac doesn't give an answer, and Fricas seems to return the same thing as 
Sage...

Re: [sage-support] About binaries.

2022-10-09 Thread Henri Girard 
I forget to say : I use it too in wsl2 where I installed ubuntu 
20.04+kali (repos), because kali has kex (xserver) in deb package, then 
I can use dualboot ubuntu directly in wsl2 or kali/ubuntu which has 
sagemath-9.5

No, sagemath  version in ubuntu is 9.5.4 (probably in kinetic as I 
always use dev version)

no. Up to date binaries for Linux can be obtained via conda-forge

https://doc.sagemath.org/html/en/installation/index.html#linux

We also hope that Debian updates its own sagemath package.
