我们现在正在 rhel 7.2 版本上安装 docker
在 yum install 过程中，我们会看到以下内容
--> Finished Dependency Resolution
Error: 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 libsepol which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of libsepol 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 libsepol.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of libsepol 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 libsepol 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: libsepol-2.1.9-3.el7.i686 != libsepol-2.5-10.el7.x86_64
Error: Protected multilib versions: libselinux-2.5-15.el7.x86_64 != libselinux-2.2.2-6.el7.i686
这意味着我们可以移除安全性的 rpm -libsepol-2.1.9-3.el7.i686 and libselinux-2.2.2-6.el7.i686
为了解决这个问题，我们安装了以下额外的 rpm
libselinux-2.5-15.el7.i686.rpm
libsepol-2.5-10.el7.i686.rpm
但现在我们得到了

You could try using --skip-broken to work around the probl
