yum was not introduced until RHEL 5; up2date is used to manage updates on RHEL 4 and lower

also, just remembered RHEL 4 was end of life February 29, 2012 so you wouldn't be able to get updates for that version anymore anyway

You need to make sure rollback is configured in up2date:

up2date-config
enableRollbacks    Yes

Open in new window

To list available rollback:
up2date --list-rollbacks

Open in new window

not yum  (not intoduced at that time)

#up2date  prior to RHEL5

use

# up2date-config

this will produce a list with the current settings which you can edit

The rollback option in Red Hat Enterprise Linux 5 is unsupported, rollback may break the system or make it unstable.  I am not sure if you can get any rollback or updates about version 4.
