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 from the tarball (
sage-9.3/README.md and sage-9.3/src/doc/en/installation/source.rst)
I installed all the required and recommended packages for Linux Mint
(Debian, Ubuntu) pointed at source.rst (link to debian.txt was broken at
README.md) I took the advice to set export MAKE='make -j2' as I have two
cores.
[dochtml] Done building the documentation!
make --no-print-directory 'SAGE_ROOT/local/etc/sage-started.txt'
"SAGE_ROOT/build/bin/sage-starts"
Testing that Sage starts...
[2021-06-30 21:50:55] SageMath version 9.3, Release Date: 2021-05-09
Yes, Sage starts.
make[2]: Leaving directory 'SAGE_ROOT/build/make'
real 223m53,530s == 3 hours 40 minutes!!
user 459m24,031s
sys 17m32,635s
Sage build/upgrade complete!
And then I ran parallel testing:
sage -t --long --random-seed=0 src/sage/tests/parigp.py
[13 tests, 1166.50 s]
----------------------------------------------------------------------
All tests passed!
----------------------------------------------------------------------
Total time for all tests: 12934.5 seconds == 3 hours 35 minutes!!
cpu time: 39406.1 seconds
cumulative wall time: 47546.7 seconds
So, happy! ^_^
Thank you again!

Hi there!
First, I want to share my appreciation and joy for this software Sage,
that I really love. Thank you all the developers that continue growing
SageMath everyday. Thank you.
Today, I've upgraded to 9.3. I've been using 9.0 until yesterday.
I've downloaded the binaries for my Linux Mint 18.3, that is, for
Ubuntu 16.04.
Both versions of Sage, were downloaded via torrent,
sage-9.0-Ubuntu_16.04-x86_64.tar.bz2 and
sage-9.3-Ubuntu_16.04-x86_64.tar.bz2
But this operation that worked on the notebook yesterday with Sage 9.0
gives me this error today with Sage 9.3:
In[1]:
print(version())
m=matrix(QQ,[0, 0, 2, 1])
print(m)
m_rs=m.row_space()
print(m_rs)
facet_z_plus_basis=m.right_kernel().basis()
facet_z_plus_basis
Out[1]:
SageMath version 9.3, Release Date: 2021-05-09
[0 0 2 1]
Vector space of degree 4 and dimension 1 over Rational Field

I've attached a notebook and html export with the full traceback.
This code works fine on SageCell (permalink here

So, I would like to know how to fix this issue and make it work again,
without rolling back to previous version of Sage.
Looking forward for your answers.
Thanks in advance,
Share_The_Sage!
