2.4.5 Disabling ULN Package Updates

You might need to disable package updates from ULN. For example, if you deleted your system from ULN, you would edit the /etc/dnf/plugins/spacewalk.conf file and change the value of enabled flag from 1 to 0 in the [main] section, as shown in the following example:

enabled = 0
gpgcheck = 1
timeout = 120

To disable updates for particular packages, add an exclude statement to the [main] section of the /etc/dnf/dnf.conf file. For example, to exclude updates for VirtualBox and kernel:

exclude=VirtualBox* kernel*


Excluding certain packages from being updated can cause dependency errors for other packages. Your system could also become vulnerable to security-related issues if you do not install the latest updates.
