build-packages on brya failing with "emerge: there are no ebuilds to satisfy "chromeos-base/vboot_reference:0/1.0-r2802=" for /build/brya/."

[Camden Bickel]

I'm seeing an error trying to `build-packages` for brya. I did the following steps to create a new checkout of ChromiumOS, which is where I'm seeing these issues:

1. Fresh `repo init` (stable) of ChromiumOS with command `repo init -u https://chrome-internal.googlesource.com/chromeos/manifest-internal -b stable` (following docs here https://chromium.googlesource.com/chromiumos/docs/+/HEAD/developer_guide.md#get-the-source-code)

2. `repo sync`

3. `cros_sdk --create`

<weekend happened>

4. `cros workon --board=${BOARD} start chromeos-base/power_manager` and `cros workon --board=${BOARD} start chromeos-base/system_api` (since I'm developing code on those packages)

5. `repo sync -j8`

6. `cros build-packages --board=${BOARD}` (Fails! Tried re-running 3 times, even after running `repo sync` again).

I'm seeing the error message "emerge: there are no ebuilds to satisfy "chromeos-base/vboot_reference:0/1.0-r2802=" for /build/brya/".

Note: Running `cros_sdk emerge-brya` completes successfully for each package.

I'm surprised to be hitting errors like this on stable after a fresh checkout. Am I doing something wrong, is the build broken, or is something else going on? 

Thank you!

I resolved this issue by repo syncing + retrying the failing command a few times. I guess it was flaky?

[Mike Frysinger]

that failure shouldn't have happened, but i can't explain why it did.  it should have rebuilt that package from source.

that said, the dep that broke you is stricter than it needs to be, so i posted a CL to relax it and you should never hit it again -- at least, via that particular code path :/.
