启动更新时,在实际更新之前会自动执行运行状况检查。如果更新运行状况检查失败,会导致更新中止(请参见下例)。更新运行状况检查仅验证可能影响更新的问题。

A health check will validate system readiness before an update is attempted, and may also be executed independently using the check command. Are you sure? (Y/N) error: System is not in an upgradeable state: prerequisite healthcheck reports problems. See alert log for more.
