Comment 1

[Silaghi Andreea]

Hi @aryx
We are not sure what caused this, we noticed this is a new job that doesn't run normally in autoland or central and we found this revision, that is making changes in that manifest but it looks like the timing doesn't fit since that got merged to central in the previous push and the job did not run.
Could you please take a look? Thank you.
