helm: v3.12.0 Failed deployments

I have the same issue, It doesn’t seem to have anything to do with any helm repo. I’m using it to deploy a local (on-disk) helm chart. Seems to have something to do with the connection to the cluster.

EDIT I fixed it by downgrading to previous helm version.

For other people, like me that is using Gitlab CI.

- curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/main/scripts/get-helm-3
- chmod +x get_helm.sh && ./get_helm.sh --version v3.11.3

Note: make sure bash and openssl is installed first.

Kubernetes patch release scheduled for 2023-05-17

@joejulian added debug variable to my CI and upgraded to 3.12 again. Debug log is huge, and i am not really into go, but this looks intresting to me:

In particular this one:

As said, there is KAS running in my case: https://docs.gitlab.com/ee/administration/clusters/kas.html

Throwing the same command directly against my cluster works fine.

I had the issue with 3.12.0, it seems to work fine with 3.12.1

@joejulian #12096 does the job for me.

    curl -Ss https://dl.google.com/go/go1.20.4.linux-amd64.tar.gz | tar -C /usr/local -xzf-
    mv /usr/local/go/bin/go /usr/local/bin/
    
    git clone https://github.com/joejulian/helm.git
    cd helm

    git checkout client-go
    make
    cp bin/helm /usr/local/bin/

    helm version

version.BuildInfo{Version:"v3.11+unreleased", GitCommit:"54ca3a82c289907a691539f8e25c2d92ae068ba3", GitTreeState:"clean", GoVersion:"go1.20.4"}

What version of Kubernetes are y’all using?

I’ve used it both 1.24 and 1.25, same issue on both.
