conda-cpp-checks job failing across multiple projects: "tar: option requires an argument -- 'f'"

[jameslamb]

Description

Across multiple RAPIDS repos today, I'm seeing failures like the following in conda-cpp-checks CI job.

[rapids-download-from-s3] Downloading and decompressing s3://rapids-downloads/ci/raft/pull-request/2470/51cdd7d/raft_conda_cpp_cuda12_x86_64.tar.gz into /tmp/cpp_channel
tar: option requires an argument -- 'f'
Try 'tar --help' or 'tar --usage' for more information.
Error: Process completed with exit code 123.

Reproducible Example

This is happening across multiple RAPIDS repos, on PRs with unrelated changes:

Examples:

• WIP: [DO NOT MERGE] build wheels without build isolation raft#2470: (build link)
• Remove DeprecationWarnings from MG Uniform Neighbor Sample test cugraph#4722: (build link)

Notes

I strongly suspect the root cause is something like "we're getting a new version of tar" + it being incompatible with this:

https://github.com/rapidsai/gha-tools/blob/c7777380c97a1986718aeaaa1b28b9437efcf03b/tools/_rapids-download-from-s3#L23

Will try to put up a more minimal reproducible example of that.

This was fixed by these PRs:

• Add conda-package-handling. ci-imgs#197
• consider .conda files in rapids-extract-conda-files gha-tools#122

Confirmed by re-running some failed jobs, e.g. https://github.com/rapidsai/raft/actions/runs/11351488094/job/31586366449?pr=2470
