有时，Red Hat Advanced Cluster Security for Kubernetes 自动升级可能无法安装。当升级失败时，安全集群的状态消息将变为 Upgrade failed。重试 upgrade。要查看有关失败的更多信息并了解升级失败的原因，您可以在 Clusters 视图中检查安全集群行。
故障的一些常见原因如下：
- 由于缺少或不可调度的镜像，sensor-upgrader 部署可能无法运行。
-
pre-flight 检查可能会失败，无论由于 RBAC 权限不足，或者集群状态无法识别。如果您编辑了 Red Hat Advanced Cluster Security for Kubernetes 服务配置或
auto-upgrade.stackrox.io/component标签，则可能会出现这种情况。 执行升级时可能会有错误。如果发生这种情况，升级安装程序会自动尝试回滚升级。
注意有时，回滚也会失败。对于这种情况，请查看集群日志以识别问题或联系支持。
在识别并修复升级失败的根本原因后，您可以使用 Retry Upgrade 选项升级安全集群。
