查看clusterrepos，发现这个版本 commit dc9ad74ba365f4ea15d173aac999f4e8134925f9 比较旧，不是最新的

解决方法

删除 rancher 自动创建的 clusterrepos

  kubectl delete clusterrepos.catalog.cattle.io rancher-charts
  kubectl delete clusterrepos.catalog.cattle.io rancher-rke2-charts
  kubectl delete clusterrepos.catalog.cattle.io rancher-partner-charts

重启rancher

kubectl rollout restart deploy rancher -n cattle-system

查看 clusterrepo rancher-charts, 发现已经更新

查看rancher 日志，也不再报 fleet is less than the min version 相关错误
