Hi, we have used fleet in the past in version 0.3.5. However we do not plan to upgrade this setup and instread build upo a new rancher/fleet infrastructure. On the Newest Rancher(v2.8.2) with fleet (v0.9.0) whenever i create a GitREpo REssource, even through the UI i get the following error in the pod trying to get the repo:

fleet HOSTNAME=k8s-pes-gitlab-4c100-x2sfm

For Reference this is what the GitRepo Ressource looks like:

apiVersion: fleet.cattle.io/v1alpha1
kind: GitRepo
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"fleet.cattle.io/v1alpha1","kind":"GitRepo","metadata":{"annotations":{},"name":"k8s-DEP-gitlab","namespace":"fleet-default"},"spec":{"branch":"rancher04","clientSecretName":"k8s-rancher-fleet-github-ssh-key-pair","helmSecretName":"company-cacerts","insecureSkipTLSVerify":false,"paths":["k8s-DEP-gitlab"],"repo":"git@github1.vg.company.int:adp/k8s-rancher-fleet.git","targets":[{"clusterSelector":{"matchLabels":{"company/department":"DEP","company/project":"gitlab"}}}]}}
