Thanks @mahendrapaipuri - that's a good start! I think I've seen this browser_check test twice, we will need to restore that one too.

Then there was a problem with the test-ui step of the CI, and also with the automated update of the snapshots, but I can do without them for now, no pressure!

It is coming from upstream JupyterLab for the latest 4.3.3 version. Seems like empty LANG locale setting is causing the error

@mwouts Could you point to the CI run where update snapshots is failing?

Yes! I think this one was the last time I tried: https://github.com/mwouts/jupytext/actions/runs/12338406420

I think extension check test is "fixed" temporarily until the upstream fixes the issue in JupyterLab.

Thank you @mahendrapaipuri . I also had to deactivate the UI tests:

https://github.com/mwouts/jupytext/blob/main/.github/workflows/step_tests-ui.yml#L46-L47

The last time I saw the UI test fail was this run: https://github.com/mwouts/jupytext/actions/runs/12338902735/job/34434556533

Heads up, setting export LANG="en_US.utf8" should no longer be needed since release of JupyterLab 4.3.4 today. The issue appears to ultimately be a bug in headless chrome distribution (see the links in the JupyterLab issue jupyterlab/jupyterlab#17079)
