This box uses sudoedit for better security. This is an example. Other tools could archive the same goal too. If this example does not work for you or if you are not using Whonix, please see this link.

sudoedit /etc/sdwdate-gui.d/50_user.conf

  1. Qubes bug report:
  2. Qubes users might want to use folder /usr/local/etc/sdwdate-gui.d in TemplateBasedVMs instead since that folder would persist after reboot and does not require changes in TemplateVM.

    Create folder /usr/local/etc/sdwdate-gui.d.
    sudo mkdir -p /usr/local/etc/sdwdate-gui.d
    Then edit file /usr/local/etc/sdwdate-gui.d/50_user.conf instead.
