I show the file still available, but amzn2 is failing to download, a mismatch in the md5 or something possibly? Current repo maintenance or a recent maintenance that put the repo in a weird state?

http://packages.couchbase.com/releases/couchbase-server/community/amzn/2/x86_64/couchbase-server-community-6.6.0-amzn2.x86_64.rpm: [Errno -1] Package does not match intended download. Suggestion: run yum --enablerepo=couchbase-server-community clean metadata
No cleaning of the metadata is helping. This is a newish problem, I’m sure I downloaded it a month ago.
