Boy, I tell ya, the more I learn about linux, the more I love it. Especially, yum. Something was wrong after I used yum to update a package. I didn’t have time to look into it in detail, so I just wanted to back out the change and downgrade the packages that were updated during the update and restore functionality. My initial thought was to restore a snapshot of the system from the night before, but I thought better and decided I would try to rollback the installation and downgrade the application. This is what I did:<\/p>\n
Got a list of all the yum transactions on the system using the yum history command:<\/p>\n
# yum history list all
