    The template is not valid. /home/runner/work/secp256k1/secp256k1/./.github/actions/run-in-docker-action/action.yml (Line: 40, Col: 7): Required property is missing: shell

    should be fixed by force-push

    The shell problem is resolved now, but the underlying issue seems unchanged.

    Yes, it is because of sysctl: permission denied on key "vm.mmap_rnd_bits", ignoring
