I agree, I wanted to see if it can be used to update to yarn 2 (so yarnpkg just becomes an installer for yarn 2). I was able to use yarn 2 successfully in gitlab.

This commit makes the switch to yarn 2.

I think the failure is after it downloaded. I can see some files in ~/.cache/yarn created after it is cleaned after yarnpkg add. Could it be a problem with extracting the tar ?

It helps if you switch to yarn 2 by running yarnpkg set version berry. See the patch linked above for gitlab. It was failing with yarn 1, but worked after switching to berry.

We cannot set version to berry globally, it has to be set per project.

I think we need to revert this patch and fix the error.
