How to disable updates available message in Discover?

us flag

I am running Kubuntu 22.04.

Sometimes, right after startup, Discover shows "Update available" in its tray icon.

I update my system regularly from the command line, and don't want to see this "Update available" message. How to disable it?

In the system tray is usually an icon you can use to show hidden icons. Select this icon with a rightclick and select Configure System Tray... from the context menu. In the System Tray Settings-window chose the Entries-Tab and there chose the desired action for Updates: enter image description here

If you don't want Discover to check for available updates at all:

It's a program called DiscoverNotifier which is checking for available updates. Seems it only checks if updates are available, the package list seems to be only updated when you click the icon which will open Discover then and fetch the updates.This program is launched in the background through a .desktop-file in /etc/xdg/autostart.

Remove the file /etc/xdg/autostart/ so DicoverNotifier will not be started automatically. To reenable, simply copy the file from /usr/share/applications/ back to /etc/xdg/autostart/.

This program also provides the system tray icon which will not be available at all if the program is not running.

I sit in a Tesla and translated this thread with Ai:

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
