The barman-cloud plugin's sidecar uploads via boto3. Since botocore ~1.36
(early 2025) the default RequestChecksumCalculation is when_supported, which
attaches a flexible checksum to every PutObject. Non-AWS S3-compatible
backends (Ceph RADOS Gateway, some MinIO / Cloudflare R2 builds) reject the
accompanying header with "InvalidArgument: x-amz-content-sha256 must be
UNSIGNED-PAYLOAD, STREAMING-AWS4-HMAC-SHA256-PAYLOAD or a valid sha256
value", so every backup/WAL-archive upload fails against them.
Pin the sidecar to when_required via the ObjectStore's
spec.instanceSidecarConfiguration.env (botocore honors the
AWS_REQUEST_CHECKSUM_CALCULATION env var) on both the keycloak system DB and
the postgres app (backup + recovery ObjectStores). when_required is also
accepted by AWS S3 on a plain PutObject, so it is a safe default everywhere.
This mirrors the etcd-operator fix (cozystack/etcd-operator#342, released in
v0.5.3), which applied the same WhenRequired policy to its aws-sdk-go-v2 S3
client for the same Ceph RGW backend.
