On any native powerpc64le-unknown-linux-gnu run with -b, this mapping lets check_host() succeed, but download_binary() then constructs a dashcore-<version>-powerpc64le-linux-gnu.tar.gz name that is unconditionally rejected at lines 164–170 because SHA256_SUMS contains no PowerPC tarballs. Consequently the claimed support cannot download any available/default tag; add the corresponding Dash artifacts and checksums, or keep this host unsupported.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Limit the PowerPC64LE mapping to releases with official artifacts.
check_host maps PowerPC64LE hosts to powerpc64le-linux-gnu, and download_binary requests that release asset. None of the default supported releases publishes this asset, so the HEAD request fails with Binary tag was not found before checksum validation. Add the mapping only with official release artifacts, or limit it to releases that publish them. Local checksum entries alone cannot fix the missing artifacts.

Final validation — Phase 2 only (queue backlog)
The PowerPC64LE host mapping is present, but Dash's release verification data contains no corresponding PowerPC64LE archives or SHA256 entries. As a result, the newly supported host cannot successfully download any supported previous release: the request either receives a 404 or the downloaded archive fails the mandatory checksum-and-filename check.

- [BLOCKING] test/get_previous_releases.py:269: Missing prerequisite: trusted PowerPC64LE release data
This mapping makes `check_host()` accept `powerpc64le-unknown-linux-gnu` and causes `download_binary()` to request `dashcore-<version>-powerpc64le-linux-gnu.tar.gz`. However, `SHA256_SUMS` contains no PowerPC64LE archive entry, and the supported Dash release tags do not provide a corresponding verified Dash artifact. Therefore every fresh download on this newly accepted platform is nonfunctional: an unavailable artifact is rejected at the HEAD request, while any downloaded archive is rejected by the mandatory checksum-and-filename validation at lines 164-170. Add official Dash PowerPC64LE artifacts together with their independently verified checksum entries, or defer this host mapping until those release prerequisites exist; checksum bypasses are not an acceptable fix.

we don't have official builds for powerpc, do we have?
See https://github.com/dashpay/dash/releases/tag/v23.1.8
I think it should be DNM until we will have them.

Still applies (re-reviewed at 4f96c8c7): The current head still contains the PowerPC64LE mapping, while the release metadata and supported Dash tags still provide no corresponding artifact or checksum. The maintainer response also confirms that official PowerPC builds are not currently available, so the download path remains nonfunctional.

Re-review — Final validation — Phase 2 only (queue backlog)
The PowerPC64LE host mapping is present, but the release downloader has no corresponding Dash PowerPC64LE artifacts or trusted checksum entries. On a native PowerPC64LE host, the newly accepted platform therefore cannot download any supported release and the existing checksum validation also rejects an archive even if one were obtained. The prior finding remains valid.
