This pertains to installation of sage-9.7.tar.gz under WSL2. I've
found it necessary to run
cp -r $HOME/sage/sage-9.7/src/sage/ext_data/ $HOME/sage/local/lib/sage
in order for various packages to pick up code in ext_data. I'm
compiling from source. I prefer
to configure sage to compile as much as possible and to rely on
ubuntu/debian packages
as little as possible.

I frankly don't understand Debian/Ubuntu packaging of
SageMath. E.g. Sage 9.0 was never tested with Python 3.9, and
their current version of cysignals.
Surely they are trying to backport our changes, but this is
quite error-prone.
Please use conda, or build from source, or use Linux distro
with much more up to date Sage, e.g.
archlinux or Gentoo.

Hi all,
I'm trying to run sage on WSL2 (Ubuntu focal 20.04.5
LTS), and after a fresh install (sadly only version
9.0), running `sage` gives the following error.
ModuleNotFoundError: No module named 'sage.cpython.string'
I happen to know that the packages are installed
in /usr/lib/python3/dist-packages/, and
sage/cpython/string.pyx is in there.
What's particularly strange to me is that sage
/can/ find `sage.misc.banner` (which is in the same
dist-packages location). Meanwhile, I can run `sage
-python` and inspect `sys.path` manually (it has the
right dist-packages path in it), but importing
sage.all in that context fails with
"ModuleNotFoundError: No module named
'cysignals.signals'" and similar with other imports.

I understand the recommendation is to use conda or
build from source to get a version > 9.2, but is there
a quick fix I can do to link the sage-python to these
libraries? Maybe an existing trac issue I can read
through workarounds? The reason I ask is because I'm
working on a library that uses sage and it's a bit of
a pain to fire up docker (and worse, the sagemath
docker image had known issues (only just now seeing
<https://trac.sagemath.org/ticket/34242#comment:21>
that a new docker image got pushed; still, working in
docker is a bit inconvenient))
Any ideas? Further steps for investigation?
