解决multilib版本问题

Question

我使用CentOS 6.4

当我尝试安装 libgcc 时，yum install libgcc.i686我做了以下按摩。

Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:
       
         1. You have an upgrade for libgcc which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of libgcc of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude libgcc.otherarch ... this should give you an error
            message showing the root cause of the problem.
       
         2. You have multiple architectures of libgcc installed, but
            yum can only see an upgrade for one of those arcitectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.
       
         3. You have duplicate versions of libgcc installed already.
            You can use "yum check" to get yum show these errors.
       
       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).
       
       Protected multilib versions: libgcc-4.4.7-4.el6.i686 != libgcc-4.4.7-3.el6.x86_64
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles –nodigest

我该如何安装libgcc.i686？

Answer 1

似乎您libgcc.x86_64的版本与libgcc.i686您尝试安装的版本不同（4.4.7-3vs. 4.4.7-4）。尝试在安装 i686-lib 的同时更新 x86_64 lib：

yum install libgcc.x86_64 libgcc.i686

Answer 2

我在打断后遇到了这个问题yum update（在我的情况下是在 ansible 运行期间）。阅读此线程后，我最终修复了它：

package-cleanup --cleandupes

虽然在此之前我也尝试过按照@etagenklo 的建议运行命令，并且还尝试过：

yum-complete-transaction
yum-complete-transaction --cleanup-only
yum check                # report generally
package-cleanup --dupes  # report on duplicate packages in particular
