 0:13.26 isn't, please use ``./mach busted file artifact`` to report it. If ``./mach busted`` is
 0:13.27 misbehaving, you can also inspect the dependencies of bug 1543241.

Comment 1

[Alex Hochheiden [:ahochheiden]]

Glandium and I discussed this and we're assuming you happened to be on the newest autoland while it was still building the artifacts for that revision. Was this a recent fresh clone you did manually, or did you explicitly hg up autoland? If yes, then you just hit an unlucky timing.

We did discuss the possibility of a workaround for this, where if this situation is hit and the artifacts aren't available yet, we could default to the most recently build artifacts from mozilla-central which should work...

Comment 2

[Alastor Wu [:alwu]]

I always update my branch to central, not autoland. But this issue no longer happens on the latest central, I will close this bug.

Comment 3

[Mike Hommey [:glandium]]

There are only very rare occasions where central would have a failure like this one, and this is not one of them AFAICT. Going backwards from your error message: ZWciktpZTC-70WvS_5Odiw was built off https://hg.mozilla.org/integration/autoland/rev/2156bbbd6a6d095bdf5575f46dd1a48536c26190, and finished building at 2023-07-11T03:18:30.368Z. That revision was merged to mozilla-central 13 hours later.
