--- Comment #1 from Mathias LANG <pro.mathias.lang at gmail.com> ---
Please don't open bugs for testsuite transient failure without identifying
them.
What can one do here to fix this bug ? Absolutely nothing. There's no
information, so this will either get ignored or closed, but never fixed.

For reference, we know that the Github actions job sometimes have some random
failures, but they are trivial to re-trigger, and it's rather rare. We took
steps to reduce it (by introducing caching, and hence reducing network load)
but there's only so much we can do (some failures are on Github side).
