Posted: Thu Sep 12, 2019 6:34 pm
Most people how to update packages using 'yum -y update <pkg>'. However, not many people actually tried to downgrade/roll back to previous version.
For RHEL 5, one needs to specify all the packages (including dependencies) in the command line such as:
For RHEL 6 and 7, yum stores a sqlite database of information about each transaction. The history is organized terms of transaction ids and is updated every time a yum transaction affects the package configuration of the system. Mostly this database can be found in the /var/lib/yum/history/ directory.
Checking the update information on ID 10 shows systemd was updated from 219-62.el7_6.5.x86_64 to 219-67.el7_7.1.x86_64:
We can downgrade from 7.1 to 6.5 by the following undo command:
and it will roll back to 6.5.
For RHEL 5, one needs to specify all the packages (including dependencies) in the command line such as:
