Fedora DNF rollback RPM package update, removal, installation

DNF rollback RPM package update, removal or installation
DNF is a next generation package manager for RPM-based Linux distributions, commonly used in newest Fedora releases. DNF is a Yum succesor, which provides Yum backward compatibility, but one of aspects, which make DNF a powerful package manager is the ability to manage transaction history.

Using DNF, we can easily undo or redo RPM package upgrade, installation and removal. This gives us the opportunity to rollback the system, if we feel, that our recent RPM package operations disordered the system.

Below we presents, how to work with DNF transaction history on Fedora 24.

Example:

Let’s assume, that we mistakenly removed few packages from the system:

[root@fixxxer ~]# dnf remove nload iftop nethogs

How to check dnf transaction history in Fedora

The below command displays DNF transaction history starting from the latest transaction on top of the listing. It displays transaction IDs along with dates of transaction, types of actions performed and amounts of RPM packages altered:

[root@fixxxer ~]# dnf history
[root@fixxxer ~]# dnf history
ID     | Command line             | Date and time    | Action(s)      | Altered
-------------------------------------------------------------------------------
    88 | remove nload iftop netho | 2017-02-06 22:36 | Erase          |    3

How to display dnf transaction info by transaction ID in Fedora

The latest transaction displayed on top of listing is our erroneous removal of three packages, we can display information about this transaction:
