Chapter 3. Configuring DNF The configuration of DNF and related utilities is stored in the [main] section of the /etc/dnf/dnf.conf file. 3.1. Viewing the current DNF configurations The [main] section in the /etc/dnf/dnf.conf file contains only the settings that have been explicitly set. However, you can display all settings of the [main] section, including the ones that have not been set and which, therefore, use their default values. Procedure Display the global DNF configuration: Additional resources dnf.conf(5) man page on your system 3.2. Setting DNF main options The /etc/dnf/dnf.conf file contains one [main] section. The key-value pairs in this section affect how DNF operates and treats repositories. Procedure Edit the /etc/dnf/dnf.conf file. Update the [main] section according to your requirements. Save the changes. Additional resources The [main] OPTIONS and OPTIONS FOR BOTH [main] AND REPO sections in the dnf.conf(5) man page on your system. 3.3. Managing DNF plug-ins Every installed plug-in can have its own configuration file in the /etc/dnf/plugins/ directory. Name plug-in configuration files in this directory <plug-in_name> .conf . By default, plug-ins are typically enabled. To disable a plug-in in one of these configuration files, add the following to the file: 3.4. Enabling and disabling DNF plug-ins In the DNF tool, plug-ins are loaded by default. However, you can influence which plug-ins DNF loads. Warning Disable all plug-ins only for diagnosing a potential problem. DNF requires certain plug-ins, such as product-id and subscription-manager , and disabling them causes Red Hat Enterprise Linux to not be able to install or update software from the Content Delivery Network (CDN). Procedure Use one of the following methods to influence how DNF uses plug-ins: To enable or disable loading of DNF plug-ins globally, add the plugins parameter to the [main] section of the /etc/dnf/dnf.conf file. Set plugins=1 (default) to enable loading of all DNF plug-ins. Set plugins=0 to disable loading of all DNF plug-ins. To disable a particular plug-in, add enabled=False to the [main] section in the /etc/dnf/plugins/ <plug-in_name> .conf file. To disable all DNF plug-ins for a particular command, append the --noplugins option to the command. For example, to disable DNF plug-ins for a single update command, enter: To disable certain DNF plug-ins for a single command, append the --disableplugin= plugin-name option to the command. For example, to disable a certain DNF plug-in for a single update command, enter: To enable certain DNF plug-ins for a single command, append the --enableplugin= plugin-name option to the command. For example, to enable a certain DNF plug-in for a single update command, enter: 3.5. Excluding packages from DNF operations You can configure DNF to exclude packages from any DNF operation by using the excludepkgs option. You can define excludepkgs in the [main] or the repository section of the /etc/dnf/dnf.conf file. Note You can temporarily disable excluding the configured packages from an operation by using the --disableexcludes option. Procedure Exclude packages from the DNF operation by adding the following line to the /etc/dnf/dnf.conf file: Alternatively, use global expressions instead of package names to define packages you want to exclude.
