By the way, if you already have so file built from past builds, this won't fail.

Chrome gardener should be looking into this.

CL under review: https://chromium-review.googlesource.com/c/chromiumos/chromite/+/971665

Sorry for breaking this. I'll test my CL and land it asap.

I am working remotely and don't have a real chromeos device to deploy chrome. What's the easiest way to reproduce this error?

I also found ./scripts/deploy_chrome_unittest.py, which covers _COPY_PATHS_CHROME. But how do I run the test?

you can boot a VM and deploy to that

once chromite updates on the CrOS side, you'll need to do a deps roll on the Chromium side

Thanks! I haven't worked on ChromeOS for a while. So I feel I need more help.

Will deploy_chrome_unittest test this path as well? Does this test only work in the chroot?

Any instructions how to boot a VM and deploy to that? Is it like I don't really need a test image etc. As long as there's an ip we'll deploy files to the target folder on that ip address?

Anyone can help answer questions in #10? Otherwise, I'll setup a ChromeOS device with test image and test my CL.

SHould be pretty easy to use a cros VM instead of a DUT for this:

 Issue 823974  has been merged into this issue.

Thanks! Trying VM now.
