LGTM, hmm, the error looks wired

[HuijingHei]

A little confused, the error is about actions/download-artifact@v3, but what we are using is v4(without this patch), am I missing something?

[travier]

Hum, we might need to update both the download and upload one at the same time to the same version.

[travier]

Let's try it: #253

[travier]

Looks like #253 did it, as https://github.com/coreos/repo-templates/actions/runs/11973256772 failed on #267 which I think we should revert for now: #269
