Rollback is the right action that you need. How to roll back an update?
In this article I show you
Environment:
CentOS 6.6
yum
Resolution
Note: Downgrading a system to minor version (ex: RHEL6.1 to RHEL6.0) is not recommended as this might leave the system in broken state where libgcc and other libraries won't rollback as expected. Use the history option for small update rollbacks.
Note: Rollback of selinux-policy-* package to older version is not supported.
If you decide to proceed with rollback, rather then reinstall, here are the instructions:
Red Hat Enterprise Linux 6 includes the yum history module which helps to rollback any updates done with the yum command. With this command, you can choose an update yum issued and remove those selected packages. The following is an example while installing the screen package:
[root@localhost ~]# yum install screen
