Step 2: Stop PackageKit

Before disabling the PackageKit, we first need to stop it as we saw in the previous step that the service is in an active state. This means that it is running. To stop it, run the following command:

1

systemctl stop packagekit

Step 3: Mask PackageKit

In this step, we will mask the Packagekit service. Masking a service prevents the service from being started manually or automatically. To mask the service, run the following command:

1

systemctl mask packagekit

This command will create a symlink from /etc/systemd/system/packagekit.service to /dev/null.

Step 2: Unmask PackageKit

In this step, we will unmask the service. In part 1, we masked it to disable automatic updates. To unmask PackageKit, issue the following command:

1

systemctl unmask packagekit

Step 3: Start PackageKit

Now that the service is unmasked, let’s start it. To start PackageKit, we will run the following command:

1

Step 4: Verify PackageKit Status

Merienda the service is started, it is in an active state. Let’s verify it. To do that, run the following command to check the status of PackageKit:
