package.provided ACL's seem to be bad

[Jeff Mendoza]

I'm trying to 'dev_install' on my old chromebook, and am running into trouble downloading the package.provided. Full url of that it is downloading:

https://commondatastorage.googleapis.com/chromeos-dev-installer/board/daisy/canary-R60-9592.71.0/packages/package.provided

The bootstrap packages download fine, for example dhcp: https://commondatastorage.googleapis.com/chromeos-dev-installer/board/daisy/canary-R60-9592.71.0/packages/net-misc/dhcp-4.2.2-r3.tbz2

Trying to download in the browser shows:

<Error>

<Code>AccessDenied</Code>

<Message>Access denied.</Message>

<Details>

Anonymous users does not have storage.objects.get access to object chromeos-dev-installer/board/daisy/canary-R60-9592.71.0/packages/package.provided.

</Details>

</Error>

I'm not using any sort of CHROMEOS_DEVSERVER, so the fallback code is not run in the script.

I'm on the beta channel "Version 60.0.3112.80 (Official Build) beta (32-bit)"

Has anyone run into this? Do I need to be on the dev channel? Thanks!

hmm, the file doesn't actually exist.  when the default ACL denies listing access, and you try to access a file that doesn't exist, that ACL kicks in.  so you can't differentiate between "file exists but i can't read it" and "file doesn't exist" since it's an information leak.

seems to me that dev-install handles this scenario gracefully (even if the output is less than ideal).

so i guess your report is more than the dev-install output is confusing ?

Oh no, it moves on to 'install_optional_package' and then fails. Looks like emerge doesn't work without this configuration file. Found the code here: https://chromium.googlesource.com/chromiumos/platform/dev-util/+/master/dev-install/dev_install#165

I don't have my chromebook with me right now, I can get the actual emerge error text tonight.

i suspect the actual failure is something else.  if you can copy & paste the full log, it'd help.

Here is the failure

we've been wanting to kill gmerge.  we should prob accelerate that if it's causing issues.

Hi all,

When running dev_install --reinstall as sudo I get the same as Jeff above:

localhost ~ # dev_install --reinstall
To clean up, we will run:
  rm -rf /usr/local/

Install virtual/target-os-dev package now? (y/N) 
You can install virtual/target-os-dev later by typing the command: emerge virtual/target-os-dev
dev_install done. Enjoy!

Should I worry about the 'curl: (22) The requested URL returned error: 403 Forbidden' in there?

I can't find out what URL the 403 is referring to, is it related to the DHCP package before or emerge?

Also 'emerge virtual/target-os-dev' fails on anything depending on 'python_targets_python2_7', since it can't find python2.7 in /usr/bin/, since it is installed in /usr/local/bin/.

But I guess that is a separate known issue (https://bugs.chromium.org/p/chromium/issues/detail?id=701955)? 

Thanks in advance for any advise.

Best regards,
Ward
