We have started hitting cipd errors in a downstream chromium (67) fork, I wonder if one of these changes could be the cause? depot_tools is up to date.
This is the error:
________ running 'cipd ensure -log-level error -root /home/tvsdk-bot/jenkins/WS/work/chromium/ -ensure-file /tmp/tmpNWps8G.ensure' in '.'
Error: resolving package: failed to resolve package version (line 67): ambiguity when resolving the tag, more than one instance has it.
It's not clear to me how to figure out what the duplicate tags are or where they are stored (so I can inspect them), but after some poking around the cli client I can see that p.UnresolvedVersion in go.chromium.org/luci/cipd/client/cipd/ensure/package_def.go is:
chromium/third_party/android_deps/repository/com_android_support_recyclerview_v7@version:27.0.0-cr0
