git reset bb6019672cd6d91cf7a2bea936cdbfdf86d70e45 --hard
export USE_BAZEL_VERSION=3bdeaea0282a3031566d3a17756fc9d59ec7f131
./.bazelci/unused_deps.sh --check 

Note :  https://github.com/grailbio/bazel-toolchain was just transferred to https://github.com/bazel-contrib/toolchains_llvm

And causing issue with checksum update.
