从5300－11升到12时提示错误0503-466 求解决

我现在的系统是
5300-11-05-1036
想升级到
5300-12-03-1107
但是现在升级的时候就提示如下错误

总是这个样子，但是我选择的补丁明明是最新的了，
而且系统里有上面这个包的。
devices.chrp.base.rte     5.3.12.1  COMMITTED  RISC PC Base System Device
  devices.chrp.base.rte     5.3.11.3  COMMITTED  RISC PC Base System Device
而且我想用smitty 菜单删除上面的包，也提示失败不让删除，
真是搞糊涂了。
