Faculty, students, and staff can roll back packages or updates they installed using yum. 

Very occasionally, installing a package or updates with yum can yield unexpected results. Thus, yum provides the ability to roll back anything it installs. Below is an example of what these commands look like:

yum history output
# yum history Loaded plugins: package_upload, product-id, search-disabled-repos, security, subscription-manager ID | Login user | Date and time | Action(s) | Altered ------------------------------------------------------------------------------- 11 | root <root> | 2016-12-16 13:20 | Install | 8 10 | root <root> | 2016-12-16 10:38 | Install | 1 9 | root <root> | 2016-12-16 08:05 | Install | 1 8 | root <root> | 2016-12-15 15:37 | Install | 1 7 | root <root> | 2016-12-15 13:29 | Install | 10 6 | root <root> | 2016-12-15 12:55 | Install | 5 < 5 | root <root> | 2016-12-08 14:51 | I, O, U | 381 >E 4 | root <root> | 2016-12-08 14:45 | Install | 4 3 | root <root> | 2016-12-08 14:12 | I, U | 32 EE 2 | root <root> | 2016-12-08 14:11 | Install | 1 1 | System <unset> | 2016-12-08 13:50 | Install | 644


To reverse any of these yum actions, enter the following command:

Using yum undo
# yum history undo "#"

Here, the trailing # is the ID number from the yum history output.

This code will put the system packages back to the version they were running prior to this yum installation or upgrade.
