I am trying to install certbot, but got an error message:

–> Running transaction check
—> Package libselinux-utils.x86_64 0:2.0.94-5.8.el6 will be updated
—> Package libselinux-utils.x86_64 0:2.0.94-7.el6 will be an update
–> Finished Dependency Resolution
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 openssl which is missing some
        dependency that another package requires. Yum is trying to
        solve this by installing an older version of openssl 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 openssl.otherarch ... this should give you an error
        message showing the root cause of the problem.
     2. You have multiple architectures of openssl 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 openssl 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: openssl-1.0.1e-48.el6_8.4.x86_64 != openssl-1.0.1e-42.el6_7.2.i686

Could not install OS dependencies. Aborting bootstrap!

hi @qihe

can you please outline how you have gone about installing certbot (including any instructions you are following and commands you have typed)
please also outline your Operating System


My operating system should be “CentOS6.0-64 LAMP for VSI”. I just ran commend “uname -a”, and got following information:
Linux hostname 2.6.32-573.12.1.el6.x86_64 #1 SMP Tue Dec 15 21:19:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

What I did is basically follow the on-line instructions and ran following commends under the directory: /root

wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto

I got previously reported error message at following step:
[root@factory ~]# ./certbot-auto
