Sage 9.5 fails to start just after an installation

[Michal Kopčok]

I have operating system Linux Lite 6.2 that is based on Ubuntu. I installed Sage from windows package manager Synaptic that is available through Xfce menu. When I write into terminal prompt the command sage, Sage starts with info 

SageMath version 9.5, Release Date: 2022-01-30                     │
│ Using Python 3.10.6. Type "help()" for help.  

But suddenly follows some Python warnings, like
/usr/bin/python3(+0x23d9fd)[0x55b08278a9fd]
/usr/bin/python3(+0x15cdc9)[0x55b0826a9dc9]
/usr/bin/python3(_PyEval_EvalFrameDefault+0x289f)[0x55b08269484f]
/usr/bin/python3(_PyFunction_Vectorcall+0x7c)[0x55b0826a9b6c]

Plenty of similar staff and Sage start crashes with text:
#248 0x00007fda0c267dc0 in __libc_start_main_impl () at ./csu/../csu/libc-start.c:392
#249 0x000055b082777a90 in _start ()

[Inferior 1 (process 3907) detached]
30    ../sysdeps/unix/sysv/linux/wait4.c: Adresár alebo súbor neexistuje.
Saved trace to /home/michal/.sage/crash_logs/crash_ikxir8ce.log
------------------------------------------------------------------------
Unhandled SIGILL: An illegal instruction occurred.
This probably occurred because a *compiled* module has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Python will now terminate.

I use Slovak localization. "Adresár alebo súbor neexistuje." could be translated as "No file or folder." or as "File or directory does not exist.".
I do not know where the problem is and what to do to make sage working.

I am sending crash_ikxir8ce.log file as an attachment. And I am adding a print screen of  Synaptic package manager choices for Sage

Many thanks for help.

Best regards

Maybe there is something wrong in the SageMath package for your system.

Since your system is based on Ubuntu, I would advise to build SageMath from sources by following these lines:

https://sagemanifolds.obspm.fr/install_ubuntu.html

It's just a few lines to copy and paste in a terminal. The benefit is that it will provide you with the latest version of Sage (9.7).

Best wishes,

Eric.

Since ubuntu 22.04, there is  bug in jupyter python/sage apparently not disturbing people because i hardly found a work around. When starting sage or jupyter we have this problem, the file is not found. I can't remenber what the expression I put in the icon to work . I found in google.

Sorry

Than you for hint. I followed instructions from page https://sagemanifolds.obspm.fr/install_ubuntu.html and I built sage from sources and it works. A compilation lasted several hours but at last all works.

Best regards

Michal
