为什么 yum update --advisory 没有更新期望的软件包？

Issue

• 系统没有通过公告更新软件包，并抛出了错误：

      # yum update --advisory RHSA-2008:0583-4
      Loading "rhnplugin" plugin
      Loading "security" plugin
      rhel-i386-server-5 100% |=========================| 1.4 kB 00:00

      Advisory "RHSA-2008:0583-4" not found applicable for this system
      No packages needed, for security, 434 available
  

• 获取命令 yum update --advisory. 的错误

• 尝试使用命令 # yum update --advisory AdvisoryNumber 清除勘误导致以下错误：

  Command Line Error : advisory no such command.
