Checks

• I've already read https://docs.github.com/en/actions/hosting-your-own-runners/managing-self-hosted-runners-with-actions-runner-controller/troubleshooting-actions-runner-controller-errors and I'm sure my issue is not covered in the troubleshooting guide.
• I am using charts that are officially provided

Controller Version

0.9.3

Deployment Method

Helm

Checks

• This isn't a question or user support case (For Q&A and community support, go to Discussions).
• I've read the Changelog before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes

To Reproduce

1. Deploy the gha-runner-scale-set-controller helm chart via Fluxcd. Flux yaml files are added in additional context.
2. Deployment fails with error:

NAME	REVISION          	SUSPENDED	READY	MESSAGE

Describe the bug

The chart revision is used in the arc-gha-rs-controller Deployment which contains a + sign which is not allowed.

Describe the expected behavior

Succesfull deployment of arc-gha-rs-controller

I had a similar issue. I would suggest pulling from GitHub directly.

Hi! we use flux to deploy ARC to our CI clusters.

This is the yaml for the repository:

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: gha-runner-scale-set
  namespace: flux-system
spec:
  interval: 30m
  type: oci
  url: oci://ghcr.io/actions/actions-runner-controller-charts

Hello @arnauvp-factorial

EDIT: I finally have a working solution (issue with egress filtering on the cluster...)

Can you share your helmRelease manifest ? 🙏
I currently try to setup it. I have the same HelmRepository but I have the following error:

source-controller chart pull error: failed to download chart for remote reference: failed to get 'oci://ghcr.io/actions/actions-runner-controller-charts/gha-runner-scale-set-controller:0.9.3': failed to do request: Head "https://ghcr.io/v2/actions/actions-runner-controller-charts/gha-runner-scale-set-controller/manifests/0.9.3": read tcp 10.64.9.170:48980->140.82.121.33:443: read: connection reset by peer

And the chart declaration in the HR:

chart:
    spec:
      chart: gha-runner-scale-set-controller
      version: 0.9.3
      sourceRef:
