This build failed:
    https://uberchromegw.corp.google.com/i/chromeos/builders/master-paladin/builds/14252

The build presumably tried to self-destruct because of this failure in
the lakitu paladin:
    https://uberchromegw.corp.google.com/i/chromeos/builders/lakitu-paladin/builds/6135

Instead, it failed with this output:
