Package: Gnome Version: 3.30.2 There comes a senseless dialog after a manually update over Settings --> Details --> Check for updates. I use the german version of gnome. Look at the attachment wich one shows the dialog (highlighted in gray above).
I suggest that the output "your system is up-to-date" is enough (including the hook-icon!) I am using Debian GNU/Linux 10.4, kernel 4.19.0-9-amd64. regards and stay healthy Jason
