First, I tripped on this one while testing yarnpkg 1.19.1 from experimental.
For the record, this is how I found that node-lodash was the culprit:
node --trace-deprecation /usr/bin/yarnpkg install
yarn install v1.19.1

Second, this should not be an RC bug.
It's a deprecation **warning**.
And it could be easily patched out by allowing stderr in the autopkgtest.
But (and that's the third point) there's no need of that hack, because the
actual fix is easier.
The upstream commit that Jonas pointed to is on a branch (4.17.15-npm) where
upstream stores built artifacts ("binaries").
You can rebuild those binaries locally in this package sources dir with:
NODE_PATH=. node lodash-cli/bin/lodash modularize exports=node -o modules
only to find that the generated modules/_createRound.js lacks the root =
require statement
The reason is that the bundled version of lodash-cli is out of date:
grep version lodash-cli/package.json
"version": "4.17.5",
if you replace the lodash-cli dir with the current version (which is in sync
with lodash itself, 4.17.15) you get the correct file generated.
So in the future we should keep the bundled lodash-cli in sync with lodash
itself.
