In this tutorial I will show you, how to remove orphaned packages in CentOS 7 server. By orphaned packages we mean all packages which no longer serve a purpose of package dependencies.
For example, package A is depended on package B, thus, in order to install package A the package B must also be installed. Once the package A is removed the package B might still be installed, hence the package B is now orphaned package.
First check whether a
package-cleanup is available. If not, use the below command to install it:
# yum install yum-utils
Obtain List of Orphaned Packages
package-cleanup to obtain list of orphaned packages currently residing in the system:
$ package-cleanup --leaves
The above command will create a list of all orphaned packages, for review, one package per line.
Remove Orphaned Packages
yum remove to remove the entire list:
# yum remove `package-cleanup --leaves`
Note, you might need to run the above commands few times to uninstall all orphaned packages. Make sure to generate a preview of all packages to be removed and review them after each iteration.
