Summary of the bug:
build failure: https://uberchromegw.corp.google.com/i/chromeos/builders/kevin-paladin/builds/198
The log of the failed provsion:
https://pantheon.corp.google.com/storage/browser/chromeos-autotest-results/hosts/chromeos2-row8-rack9-host14/59966813-provision/debug/

It complains that client-autotest.tar.bz2 could not be fetched from any of the repos ['http://100.115.245.198:8082/static/kevin-paladin/R58-9280.0.0-rc2/autotest/packages'

I manually download the autotest_package.tar from the image https://pantheon.corp.google.com/storage/browser/chromeos-image-archive/kevin-paladin/R58-9280.0.0-rc2/. The client-autotest.tar.bz2 is actually there

Try to stage the artifact for the same build again? It could be some devserver issue. Also, check the timestamp of that client-autotest.tar.bz2 on GS, maybe there is a timing issue?

Yeah, I think all three builds 198, 197, 196 were trying to stage for the same build and failed. The timestamp for the autotest_packages.tar is 2/13/17 5:41 AM. So, I don't think it is a timing issue that can affect all three builds.

It's because host chromeos2-row8-rack9-host14.cros (100.115.231.55) fails to run 'wget --connect-timeout=15 --retry-connrefused --wait=5 -nv http://100.115.245.198:8082/static/kevin-paladin/R58-9280.0.0-rc2/autotest/packages/client-autotest.tar.bz2 -O /tmp/sysinfo/autoserv-4oNwST/packages/client-autotest.tar.bz2' command. I ssh to the host and manually run this cmd, still fail.

Instead I tried to ssh chromeos2-row6-rack5-host17.cros (100.115.228.226), and successfully executes this cmd. 

Usually the host will find a devserver in its subnet and should be able to run wget. I think there's some network config/connection issue between host chromeos2-row8-rack9-host14.cros and devserver 100.115.245.198.

So reassign to deputy to file a bug to engLab.

Issue 692161 has been merged into this issue.

This took down several paladin runs. I've locked the DUT in question. Raised to P0. We can't leave the CQ broken for extended periods like this.

to haowei@ any idea if there's been some network reconfiguration that would cause this?

Question.

How we name the path in the software? 

If this commend is correct. 
wget --connect-timeout=15 --retry-connrefused --wait=5 -nv http://100.115.245.198:8082/static/kevin-paladin/R58-9280.0.0-rc2/autotest/packages/client-autotest.tar.bz2 -O /tmp/sysinfo/autoserv-4oNwST/packages/client-autotest.tar.bz2'

I don't see the path above in that server. I only can find the package of Kevin-paladin here. 
chromeos-test@chromeos2-devserver6:~/images/kevin-paladin$ pwd
/home/chromeos-test/images/kevin-paladin

And the build number is 
chromeos-test@chromeos2-devserver6:~/images/kevin-paladin$ ls
R58-9304.0.0-rc3

I tested with current build:
wget --connect-timeout=15 --retry-connrefused --wait=5 -nv http://100.115.245.198:8082/static/kevin-paladin/R58-9304.0.0-rc3/autotest/packages/client-autotest.tar.bz2 -O /tmp/1.tar.bz2

Looks good to me
