Sage 9.5 fails to start just after an installation

savecancel

I have operating system Linux Lite 6.2 based on Ubuntu. I installed Sage from windows package manager Synaptic available through Xfce menu.

When at the terminal prompt I run 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 stuff and Sage start crashes with text:

#248 0x00007fda0c267dc0 in __libc_start_main_impl () at ./csu/../csu/libc-start.c:392
#249 0x000055b082777a90 in _start ()

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, and "adresár alebo súbor neexistuje" translates 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 work. I cannot upload here the above mentioned file crash_ikxir8ce.log because I need more than 60 points to be allowed to do so.
