Initial triage for this issue to Taskcluster/General for further triage.

Comment 2

[Chris Cooper [:coop] (he/him)]

Natalia: The link to the log isn't very useful without a corresponding link to the task and/or treeherder entry. Can you try to include those in the future, please? We can reverse-engineer them, but shouldn't have to.

Here's the task:

https://tools.taskcluster.net/groups/cXxCYFFiTMS_eAZWGhj-oA/tasks/VeaEZtTZTXqcXBYgQF5tJw/details

And here's the link to the job in treeherder:

https://treeherder.mozilla.org/#/jobs?repo=autoland&revision=318f17dbfa9f1abac4fd6035ba1a449bbc7de2e4&selectedJob=177314395
 
Doesn't look like the job was retriggered, so I've done that now and will report back.

My bad, it was retriggered, so my retriggers just added to the pile of results: 

No logs (original failure)

[Pete Moore [:pmoore][:pete]]

These are hardware workers running a very old generic-worker version. Bug 1443589 should solve this.

Mark, any ETA on that bug?

Thanks.

Comment 8

[Mark Cornmesser [:markco]]

My last run at it, I was able to get GW 10 installing and functioning with out any error. However, it failed every task I ran on it. 

pmoore: I was actually going to contact you this coming week to see if we can set up a time during the work week to meet up on work on this. I will get additional info into the pertaining to the configuration and task failures before that.

That bug is now resolved, so we shouldn't see this issue again. Should we close this bug already, or leave open to monitor?

We haven't seen this failure anymore, so I think the bug can be closed. 
If the issue reoccurs, we'll reopen it. 
Thank you!
