updateinfo info done看看inux RHSA-2020:4907 -->更新包--我可以看到包含修复程序的包:

当我检查当前版本并将其与将在更新时安装的版本进行比较时,我可以看到当前版本是freetype-2.8-14.el7.x86_64,而要安装的包版本将是包含修补程序包freetype.x86_64 0:2.8-14.el7_9.1的包版本是更新:

但我没什么问题。


有谁能解释一下吗?
谢谢!

其他软件包是同一建议的一部分,但您只需要升级它们,如果它们已经安装。debuginfo包提供调试信息,通常只有在您调查Freetype中的崩溃或使用库进行开发时才需要这些信息;demos包包含演示工具,devel包包含仅用于使用Freetype构建程序所需的开发文件。
yum update --advisory RHSA-2020:4907将为您做正确的事情:它将升级任何需要升级的软件包,而不需要额外安装任何您不需要的东西。
