在一次进行内核漏洞修复的过程中,部分包升级时出现如下冲突:
错误: 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 systemd-libs which is missing some
dependency that another package requires. Yum is trying to
solve this by installing an older version of systemd-libs 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 systemd-libs.otherarch ... this should give you an error
message showing the root cause of the problem.
2. You have multiple architectures of systemd-libs 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 systemd-libs 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).
保护多库版本:systemd-libs-219-62.el7.x86_64 != systemd-libs-219-57.el7.i686
错误:保护多库版本:libselinux-2.2.2-6.el7.i686 != libselinux-2.5-14.1.el7.x86_64
报错信息很重要!!! 报错信息很重要!!! 报错信息很重要!!!
上述报错信息中给出了可能导致该错误的原因和解决办法,即将多版本保护关闭即可:
yum install --setopt=protected_multilib=false -y 包名
