软糖不能吃
提问于 2021-06-14 12:40:41
我在CentOS8上。我正面临着类似于这个问题的情况，尝试了所有的建议，但无法解决。
我正在尝试安装ffmpeg-devel，它需要ffmpeg-lib，它需要libgcrypt。系统需要Libgcrypt，它是受保护的包，无法卸载。Libgcrypt-1.8.5-4.el8是比libgcrypt-1.5.3-14.el7更新的版本。
怎么做呢？已经持续了三天了。

您正在试图在CentOS 8上安装CentOS 7的软件包，这是行不通的。您必须安装为CentOS 8构建的相应包。
您似乎还在这个系统上为CentOS 7添加了一个yum存储库。这也将无法工作，因为它的任何软件包都不能安装。将其替换为CentOS 8的相应yum存储库。
