GH Actions: WSL workflow fails with failed syscalls

[mkoeppe]

Also reported in ​https://groups.google.com/g/sage-devel/c/jE6qf0MqriQ/m/cdsEC8SkAgAJ

To fix this, we should probably follow the guidance added in #32714, putting as much of the build in the Linux filesystem.

[mkoeppe]

Tobias, when you have a chance, could you try to fix up the WSL workflow please? It's been failing consistently for months now

[gh-tobiasdiez]

Sorry, I don't have time for this in the foreseeable future.

[mkoeppe]

Thanks for letting us know, and thanks for all your work in the past months.

It now fails during the installation of flint

Please email sage-devel (http://groups.google.com/group/sage-devel)
explaining the problem and including the log files
  /mnt/d/a/sage/sage/logs/pkgs/flint-2.7.1.log
and
  /mnt/d/a/sage/sage/config.log
Describe your computer, operating system, etc.
If you want to try to fix the problem yourself, *don't* just cd to
/mnt/d/a/sage/sage/.tox/local-sudo-ubuntu-standard/local/var/tmp/sage/build/flint-2.7.1 and type 'make' or whatever is appropriate.
Instead, the following commands setup all environment variables
correctly and load a subshell for you to debug the error:
  (cd '/mnt/d/a/sage/sage/.tox/local-sudo-ubuntu-standard/local/var/tmp/sage/build/flint-2.7.1' && '/mnt/d/a/sage/sage/sage' --buildsh)
When you are done debugging, you can type "exit" to leave the subshell.
************************************************************************

Seems to be a version mismatch between flint and bits. I cannot reproduce it locally.

[mkoeppe]

Looks to me like a failed system call when accessing this header file. Is this appearing in more than one run?

[gh-tobiasdiez]

Yes, flint fails since 9.4.beta6 see ​https://github.com/sagemath/sage/actions/workflows/ci-wsl.yml

[mkoeppe]

Is this using WSL 1 or 2? Should we test both?

[gh-tobiasdiez]

WSL 1 is the only supported version (WSL 2 would require a self-hosted runner).

[chapoton]

bump to 9.6

[mkoeppe]

This ticket needs some care so that we can update our instructions for WSL to something that actually works.
