The Manifest files in this repository are using obsolete hashes RMD160 or WHIRLPOOL. Please update to newer Manifest hashes to avoid problems with newer package managers. For more information, see the tracker blocked by this bug.
In metadata/layout.conf, manifest-hashes was changed to "BLAKE2B SHA512" a couple of months ago. i've scanned the repository for RMD160 and WHIRLPOOL hashes and found none. As recommended, I've gone ahead and commented out the manifest-hashes setting and rebuilt the manifests...ended up with no changes, according to git. My repo should be good to go.
