unexpected EOF while push to public oci repo

[gjenkins8]

Latest working helm version is v3.13.1
all newer version till v3.14.2 won't work.

We attempt to support basic auth #12237, but due to the lack of standardization of OCI authentication, doing so broke (1, 2) many other registries.

The reason Helm 3.13.1 works, is it did contain this functionality, but it was reverted v3.13.2 onwards.

A concrete proposal/specification on how to support different authentication types for different registries would be needed to more forward at this point IMHO.

@gjenkins8 That's what I'm wondering. I compared the two releases and it seems the feature are reverted.

Nevertheless newer versions didn't work for me. I compiled commit by commit with these results:

3547a4b: OK (v3.13.1)
99ce118: OK
268dced: OK
e785e6c: NOT OK
3b4cacf: NOT OK
10018ff: NOT OK
7e0084a: NOT OK
666b199: NOT OK
12826e8: NOT OK
00a334c: NOT OK
8f554be: NOT OK
2a2fb3b: NOT OK (v3.13.2)

Let's concentrate on e785e6c

The docker client auth in pkg/registry/client.go:96 was completely removed. For me as an enduser it looks like that I need at least Authorization header with bearer token/password to keep the upload working:

               dockerClient, ok := client.authorizer.(*dockerauth.Client)
               if ok {
                       _, password, err := dockerClient.Credential(ref.Registry)
                       if err != nil {
                               return nil, fmt.Errorf("unable to retrieve credentials: %w", err)
                       }
                       headers.Set("Authorization", fmt.Sprintf("Bearer %s", password))
               }

$ helm version                                                           
version.BuildInfo{Version:"v3.13+unreleased", GitCommit:"e785e6c50c622ed5019fd4020a13509c87a3022d", GitTreeState:"dirty", GoVersion:"go1.22.1"}

$ helm push crossplane-1.15.0.tgz oci://mtr.devops.telekom.de/caas/charts

I think the newer Go version can be ignored.
