我正在从规范文件创建 RPM。我正在安装 java8 最新版本作为依赖项，它总是工作正常。今天我需要将 java8 版本固定到特定的版本，但出现错误。我在规范文件中更改的内容来自：
Requires: java-1.8.0-openjdk-devel
到
Requires: java-1.8.0-openjdk-devel = 1:1.8.0.252.b09
可以看到版本1:1.8.0.252.b09-2.el6_10是可用的，那为什么会出现这个错误呢？

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
