Thanks for your reply.
Yes, I see the updates are downloaded automatically. I regularly see that notification in the upper right corner of the screen.
I found the Alerts and Notifications options, those are checked. But I am not seeing them appear on the desktop...
I am on Netrunner Rolling release, this is an Arch / Manjaro based distribution. I know NOD32 is not written for systemd. Someone posted instructions for creating a unit file, and starting the service at boot. That allowed me to access the gui.
Maybe there is more I need to do to the alerts / notifications to display on the desktop?
Thanks for any info.
