@jyoungyun Looks like the build succeeded but was marked as failed in CI above. Here is the output from the log (https://ci.dot.net/job/dotnet_core-setup/job/master/job/release_ubuntu_arm_prtest/2/consoleFull):

Can you PTAL?

Also, can you please add Ubuntu 16.04 Arm32 CI support as well at https://github.com/dotnet/core-setup/blob/master/netci.groovy#L13?

I think following line 215 of scripts/arm32_ci_script.sh should be updated, it's valid at coreclr and corefx but not in core-setup.

 sudo chown -R $(id -u -n) ./bin

Related log:

18:14:44 + sudo chown -R dotnet-bot ./bin
18:14:44 chown: cannot access ‘./bin’: No such file or directory

BTW How can make a link to the line ? It seems that github don't provide a link for unmodified line.

@gkhanna79 I fixed the arm32 CI script. And it works well! :) And acutally I wanna add Ubuntu 16.04 Arm32 CI but I'm not sure what images will work well for our CI job. Anyway I will try it. I think maybe 'latest-or-auto-docker' in 'Ubuntu16.04' will support our CI job without any problems. I will make another PR for supporting Ubuntu 16.04 arm CI job. This PR is ready to merge. PTAL~

[gkhanna79]

I have merged this @jyoungyun. Please kick off a dummy PR to confirm everything looks good.
