Syncing rhel 8.4 base os kickstart results in an error:

digging around the metadata, i didn't see any md5 checksums anywhere except for the 'extra_files.json':

}

In my case i had sha1 and sha256 enabled, but not md5. I don't think pulp should validate ALL the checksums if those particular checksums aren't enabled within pulp.

And its possible that i'm barking up the wrong tree with this extra_files.json, its just the only file i could find in all the metadata (including treeinfo) that included an md5 checksum
