Chapter 5. Removing RHEL 8 content
The following sections describe how to remove content in Red Hat Enterprise Linux 8:
- Section 5.1, “Removing installed packages” describes removing a package.
- Section 5.2, “Removing installed modular content” describes removing content installed from a module stream or a profile.
- Section 5.3, “Resetting module streams” describes resetting module streams to initial state.
- Section 5.4, “Commands for removing content” summarizes the commands for removing content.
5.1. Removing installed packages
This section describes how to remove packages.
Procedure
Remove the package:
# yum remove package
The package is removed together with any other dependent packages.
5.2. Removing installed modular content
When removing installed modular content, you can remove packages either from a selected profile or from the whole stream.
YUM will try to remove all packages with a name corresponding to the packages installed with a profile or a stream, including their dependent packages. Always check the list of packages to be removed before you proceed, especially if you have enabled custom repositories on your system.
5.2.1. Removing all packages from a module stream
When you remove packages installed with a module stream, all packages with a name corresponding to the packages installed by the stream are removed, including their dependencies, with the exception of packages required by other modules.
Prerequisites
- The module stream has been enabled and at least some packages from the stream have been installed.
- You must understand modular dependency resolution.
Procedure
Remove all packages from a selected stream:
# yum module remove --all module-name:stream
Replace module-name and stream with the module and stream you wish to uninstall.
-
Check the list of packages under
Removing:
andRemoving unused dependencies:
before you proceed with the removal transaction. - Optionally, reset or disable the stream.
If you want to remove only packages from a selected profile, follow instructions in Section 5.2.2, “Removing packages from an installed profile”.
Example 5.1. Removing packages from the whole stream
This example shows how to remove all packages from the module stream.
Procedure
Install the
php:7.3
module stream, including all available profiles:[root@rhel-8 ~]# yum module install php:7.3/* Updating Subscription Management repositories.

5.2.2. Removing packages from an installed profile
When you remove packages installed with a profile, all packages with a name corresponding to the packages installed by the profile are removed, including their dependencies, with the exception of packages required by a different profile.
Prerequisites
-
The selected profile has been installed using the
yum module install module-name:stream/profile
command or as a default profile using theyum install module-name:stream
command. - You must understand modular dependency resolution.
Procedure
Uninstall packages belonging to the selected profile:
# yum module remove module-name:stream/profile
Replace module-name, stream, and profile with the module, stream, and profile you wish to uninstall.
Alternatively, uninstall packages from all installed profiles within a stream:
# yum module remove module-name:stream
These operations will not remove packages from the stream that do not belong to any of the profiles.
-
Check the list of packages under
Removing:
andRemoving unused dependencies:
before you proceed with the removal transaction.
To remove all packages from a selected stream, follow instructions in Section 5.2.1, “Removing all packages from a module stream”.
Example 5.2. Removing packages from a selected profile
This example shows how to remove packages belonging only to a selected profile.
Procedure
Install the
php:7.3
module stream, including all available profiles:[root@rhel-8 ~]# yum module install php:7.3/* Updating Subscription Management repositories.

5.3. Resetting module streams
Resetting a module is an action that returns all of its streams to their initial state - neither enabled nor disabled. If the module has a default stream, that stream becomes active as a result of resetting the module.
Procedure
Reset the module state:
# yum module reset module-name
The module is returned to the initial state. Information about an enabled stream and installed profiles is erased but no installed content is removed.
5.4. Commands for removing content
This section lists commonly used commands for removing content.
Command list
- Remove a package
# yum remove package
- Remove packages from an installed profile
# yum module remove module-name:stream/profile
- Remove all packages from an active stream
# yum module remove --all module-name:stream
- Reset a module to the initial state
# yum module reset module-name
- Disable a module and all its streams
# yum module disable module-name
