+The "Missing Location" message is generated by the aws library when a
+multipart upload results in a response from the S3 server that does not
+include a Location tag.
+
+You should be able to verify this by passing --debug to see the http
+response.
+
+This is documented in the AWS API
+[here](https://docs.aws.amazon.com/AmazonS3/latest/API/API_CompleteMultipartUpload.html#AmazonS3-CompleteMultipartUpload-response-Location).
+
+I suspect this is (another) respect where the Garage server doesn't
+implement the API quite right..
+
+It would be possible to change the aws library to not throw an error here,
+and git-annex is not actually using that Location tag for anything. But it
+seems like it would probably be better to fix Garage.
+
+Setting chunk= rather than partsize= should be an easy workaround for the
+problem.
