pushing charts fails - encryption method issue

[eilonk]

Hi, i'm breaking my head over this problem with chartmuseum and can't find any issues on this. i configured chartmuseum on my aws environment and everything seems fine (the url shows the welcome page, all pods have no errors) I configured a directory in my computer to serve as a repo, as instructed.

when i try to push the charts (.tgz) to the chartmuseum, i get an error:

Error: 500: InvalidArgument: The encryption method specified is not supported
status code: 400, request id: xxxx, host id: xxxx

*xxx mark sensitive data

steps i did to try and solve this:

• unpacked the .tgz files and repacked them (error still shows)
• used helm push with --force, --insecure
• tried to send the charts with curl, wput, repo update and helm push
• re-initialize the helm client

did anyone encounter this error? I ran out of ideas regarding how to fix this, any ideas would be great Thanks!

This is caused by AWS SSE not being configured correct.

See the notes from the AWS bucket provider:

    // The server-side encryption algorithm used when storing this object in Amazon
    // S3 (for example, AES256, aws:kms, aws:kms:dsse).
    ServerSideEncryption *string `location:"header" locationName:"x-amz-server-side-encryption" type:"string" enum:"ServerSideEncryption"`

https://docs.aws.amazon.com/sdk-for-go/api/service/s3/s3manager/

Setting STORAGE_AMAZON_SSE: aws:kms fixed this for me.
