The edited comment should have the info. The code change looks large, but its copied from the install_cache script that our docker images use https://github.com/pytorch/pytorch/blob/6a8006472e431f872ca40c7aad250b61105de583/.ci/docker/common/install_cache.sh#L42 Sccache stopped working on xla at some point near dec 17 2023. I am not sure what commit caused it. I think it was having trouble writing to the cache. Either way, there is an sccache already installed on the docker image, so we should use that instead of a binary from s3 which we're probably no longer sure where it came from/what commit it was built from The one in the docker image is installed here https://github.com/pytorch/xla/blob/69d438ee65cc250c974ca80edd80462ffbb2e163/.github/upstream/Dockerfile#L61 and is also very old, so I have pytorch/xla#9102 to update it sccache still not writing properly, i will investigate, but xla build currently broken after the above xla pr, and this should fix it Pull Request resolved: #153002 Approved by: https://github.com/malfet (cherry picked from commit cbcb57d)

Sccache stopped working on xla at some point near dec 17 2023. I am not sure what commit caused it. I think it was having trouble writing to the cache.
Either way, there is an sccache already installed on the docker image, so we should use that instead of a binary from s3 which we're probably no longer sure where it came from/what commit it was built from
The one in the docker image is installed here https://github.com/pytorch/xla/blob/69d438ee65cc250c974ca80edd80462ffbb2e163/.github/upstream/Dockerfile#L61 and is also very old, so I have pytorch/xla#9102 to update it
sccache still not writing properly, i will investigate, but xla build currently broken after the above xla pr, and this should fix it
