我无法完成 yum 更新，如果我没有看错的话，我的系统认为它同时是 32 位和 64 位。

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 mesa-libglapi which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of mesa-libglapi 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 mesa-libglapi.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of mesa-libglapi installed, but
yum can only see an upgrade for one of those architectures.
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 mesa-libglapi 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: mesa-libglapi-17.0.1-6.20170307.el7.i686 != mesa-libglapi-17.2.3-8.20171019.el7.x86_64
我尝试过
package-cleanup --dupes
package-cleanup --cleandupes
yum clean all
yum update
我已多次重启，并下载了 mesa-libglapi-18.0.0-4.fc29.x86_64.rpm，并尝试使用 yum localinstall 和 rpm -Uvh 手动更新软件包，但均失败
yum localinstall:

答案1
当您看到“受保护的多库版本”消息时，您需要运行yum distro-sync而不是yum update在这里。
顺便说一句，在 RHEL 7.5 中，该gnome-shell-extension-top-icons软件包从 移至rhel-7-server-rpms，rhel-7-server-optional-rpms因此您需要确保在将现有 GUI 系统从 7.x 升级到 7.5 之前已启用可选频道。
