[Bug] YN0018 in github actions when using TypeScript

Describe the bug

yarn install fails with on GitHub actions but not locally with YN0018

• yarn cache clean --all did not help
• updating yarn to latest did not help
• updating yarn to sources did not help

Also tried:

/D/p/m/typescript-to-proptypes (master|✔) $ yarn -v
2.0.0-rc.31.git.20200327.c2902096
~/D/p/m/typescript-to-proptypes (master|✔) $ yarn cache clean --all
➤ YN0000: Done in 0.07s
~/D/p/m/typescript-to-proptypes (master|✔) $ set -x YARN_CHECKSUM_BEHAVIOR update
~/D/p/m/typescript-to-proptypes (master|✔) $ yarn

which did not change anything. The install did take quite a while though. It seemed to be frozen after it downloaded everything.

To Reproduce

1. Clone https://github.com/merceyz/typescript-to-proptypes
2. yarn install
3. works fine
4. same commit fails in github actions: https://github.com/merceyz/typescript-to-proptypes/runs/547813870

My best guess is that this is due to this change, committed a few weeks ago: https://github.com/yarnpkg/berry/blob/master/packages/plugin-patch/sources/patchUtils.ts#L143

It slightly changed the patch mechanism with regard to line endings to make it more consistent, but unfortunately it was already too late and I should have bumped the cache version since the old one wasn’t compatible with the new one anymore.

To workaround this, try the following:

• yarn cache clean --all

At this point, running yarn install should start to fail. Then run this:

• YARN_CHECKSUM_BEHAVIOR=update yarn

It’ll update the lockfile with the new cache checksums.

I get this with Yarn 2 on Github CI but only with a git repo dependency:

https://github.com/LearnSomethingTeam/mathjs.git#commit=3c3048bedb39db7352bec75846ed6e8a04b9f862

“The remote archive doesn’t match the expected checksum”

I do use Typescript

When I set YARN_CHECKSUM_BEHAVIOR=update the CI build succeeds, but I’d really rather not use that.
