  • How to get rid of the System Not Registered notification from GNOME?

Resolution

Be warned that Red Hat does not recommend disabling the System Not Registered notification.

For RHEL 9 systems

  • Masquerade the user service globally, running this command as root:

    # systemctl --global mask org.gnome.SettingsDaemon.Subscription.service

  • Alternatively, masquerade the service for a single user, running this command as that user:

    $ systemctl --user mask org.gnome.SettingsDaemon.Subscription.service

  • Remove the subscription-manager-cockpit package to disable RHSM cockpit UI notification:

    # yum remove subscription-manager-cockpit

For RHEL 8 systems

  • Edit /etc/xdg/autostart/org.gnome.SettingsDaemon.Subscription.desktop and comment out the line containing Exec=/usr/libexec/gsd-subman as shown below:

    # sed -i -e '/^Exec=/s/^/#/' /etc/xdg/autostart/org.gnome.SettingsDaemon.Subscription.desktop

    Note: The above change may be reverted if the gnome-settings-daemon and subscription-managerpackages are updated on the system.

  • Remove the subscription-manager-cockpit package to disable RHSM cockpit UI notification:

    # yum remove subscription-manager-cockpit

Root Cause

  • In RHEL 9 systems, the System Not Registered notification is managed by the GNOME Subscription Management service which is triggered by the file /lib/systemd/user/org.gnome.SettingsDaemon.Subscription.service.

  • In RHEL 8 systems, the System Not Registered notification is managed by the GNOME Subscription Management service which is triggered by the file /etc/xdg/autostart/org.gnome.SettingsDaemon.Subscription.desktop.

  • The Subscription-Manager Cockpit UI is provided by the subscription-manager-cockpit package.
