I'm also seeing illegal instruction in Sage 9.3 and 9.4 (and not in 9.2)
while doing some linear algebra, although I'm not sure if it's the same bug
or not.
In either case, my bugreport is submitted
to https://trac.sagemath.org/ticket/32447

I suspect the cause is OpenBLAS. While this library is built with
DYNAMIC_ARCH=1, there is still the non-performance critical code which will
use whatever instructions are available on the machine at compile time
unless you also set TARGET. See
https://github.com/xianyi/OpenBLAS/issues/3056
Would it help to set `CFLAGS` to `-mno-avx -mno-avx2 -mno-bmi2`
as is done for building the Sage macOS app? --Samuel

Hi,
I release cocalc-docker ([1], [2]) a few days ago with sage-9.4, and had
people reporting back "illegal instruction" issues. Sage is built there
with SAGE_FAT_BINARY="yes", using this script [3]. One person who reported
a problem had a "Dell PowerEdge R710." and I built on an intel Dell
In the end I build 9.4 from source and that worked perfectly. And it turned
out that the Ubuntu 18.04 binaries of 9.2 also work on this particular
machine (though we went for 9.4 in the end). Thanks again for the help.

Thanks, I'll do that.

These "illegal instruction" errors are an indication that the binary was
built for a more advanced CPU than yours - which does not support certain
CPU commands. It's a bug in "fat binary" build process we see for some time.
Build Sage yourself, or use Conda.

Hi Marco, How are you?
In my case, upgrading to Ubuntu 20.04 base, didn't solve the issue.
Building did.
I had the same SignalError on Linux Mint 20.1 (based on Ubuntu 20.04)
with the corresponding Sage prebuild binaries as in Linux Mint 18.3
(based on Ubuntu 16.04).
So, I took courage and
Hi everyone,
I'm having the same problem, on Ubuntu 18.04:
I unpack the binaries sage-9.3-Ubuntu_18.04-x86_64.tar.bz2 and run ./sage
Then I see a few lines that look like
/home/strengtc/software/sage-9.3/local/lib/python3.9/site-packages/traitlets/config/loader.py:795:

Hi there!
I've upgraded to Linux Mint 20.1 Ulyssa (kernel 5.4.0-77-generic), and
then I've build Sage 9.3 from source.
Now the issue is solved. Thanks for this amazing software!
I downloaded sources tarball for sage 9.3 via torrent. Then, before
proceeding, I studied README.md and source.rst
