Wasabi S3 Errors

[r1chjames]

I've been using Wasabi S3-compatible storage using CNPG, however recently my backups have been failing with the following error:
failure uploading data (An error occurred (InvalidRequest) when calling the UploadPart operation: Checksum Type mismatch occurred, expected checksum Type: null, actual checksum Type: crc32).

I can't pinpoint when it stopped working, however I'm running with the following config:

backup:
    barmanObjectStore:
      destinationPath: 's3://[REDACTED]-cnpg-backups/shared'
      endpointURL: 'https://s3.eu-west-1.wasabisys.com'
      s3Credentials:
        accessKeyId:
          name: wasabi-secret
          key: ACCESS_KEY_ID
        secretAccessKey:
          name: wasabi-secret
          key: ACCESS_SECRET_KEY

I'm unsure whether it's related to the change to 3.12, just wondering if anyone else had seen something similar. I've moved to AWS S3 and it works so presumably it's a specific issue in the Wasabi implementation of S3 API.

I had the same issue (unrelated to barman). It started happening when I upgraded to boto3 1.36.13. After I downgraded to 1.35.19 the issues were resolved.

I am not sure of what is causing this exactly though.

@f-prime Boto3 1.36 introduced a breaking change. That's why in Barman we are pinning 1.35.99 to our Barman builds until we provide the needed changes for 1.36.x to work
