不同架构的 Yum 包冲突

我有一台运行 CentOS 5.5 的机器，我想升级到最新的 5.x 版本。它遇到了 freetype 问题。

Freetype 安装了 i386 和 x86_64 版本。这是正常的，但 x86_64 版本要新得多（反向移植了 2.4 以支持其他几个软件包；我甚至没有 32 位机器来构建 i386 版本）。

[sh-beta@localhost ~]$ yum list installed | grep freetype
freetype.i386                       2.2.1-28.el5_7.2                   installed
freetype.x86_64                     2.4.8-1                            installed
[sh-beta@localhost ~]$ yum list updates | grep freetype
freetype.i386                     2.2.1-31.el5_8.1              updates         
[sh-beta@localhost ~]$ sudo yum -y update freetype.i386

在这台测试机上，我可以手动将 x86_64 包降级到基础 CentOS 5.5 版本，然后再将两者都升级到 5.8 版本，没有任何问题。

[sh-beta@localhost ~]$ sudo yum -y downgrade freetype-2.2.1-28.el5_7.2.x86_64
<...snip...>
[sh-beta@localhost ~]$ yum list installed | grep freetype
freetype.i386                       2.2.1-28.el5_7.2                   installed
freetype.x86_64                     2.2.1-28.el5_7.2                   installed
[sh-beta@localhost ~]$ sudo yum update freetype-2.2.1-31.el5_8.1
<...snip...>
[sh-beta@localhost ~]$ yum list installed | grep freetype
freetype.i386                       2.2.1-31.el5_8.1                   installed
freetype.x86_64                     2.2.1-31.el5_8.1                   installed
[sh-beta@localhost ~]$

这是怎么回事？我该如何修复？由于我还有其他依赖 2.4 的软件包，因此降级是我服务器上的最后手段。

如果您不需要 i386 版本，freetype请将其删除：

  • rpm -e freetype.i386

如果您需要它，或者其他系统包依赖它，请执行以下操作：为 i386 重建它。如果您仍然拥有反向移植时生成的源 RPM，那么这非常简单。

  • 安装 EPEL 存储库
  • yum install mock
  • mock -r epel-5-i386 freetype-2.4.src.rpm
