From time to time, AppCenter will find an update and hang out in my dock with a red, circular "badge" overlay and a number.


  • How can I deactivate this persistent dock notification?
  • Separately, how do I stop AppCenter from automatically checking on updates?

The AppCenter periodically shows updates because it runs in the background on startup. To disable its notifications, set it to not run on startup:

  1. mkdir ~/.config/autostart/

  2. cp /etc/xdg/autostart/io.elementary.appcenter-daemon.desktop ~/.config/autostart/

    This copies the AppCenter startup directions from the general autostart folder to your personal folder. (The startup process prioritizes directions given in the latter.) Then modify the new file to not load on startup:

  3. echo "X-GNOME-Autostart-enabled=false" | tee -a ~/.config/autostart/io.elementary.appcenter-daemon.desktop

  4. reboot

If you would like to keep AppCenter running but just remove the badge, there is currently no configuration setting for this. (Badge counts are hardcoded in their other instances.) If you'd like to build your own version without notifications, start with modifying /src/Core/Client.vala and /src/Widgets/AppCellRenderer.vala in the source code.


To the first question, you can open a terminal and type:

killall appcenter

Now the reminder dessapears from Planck.

To the second question, you can try to show all the hidden startup applications. Open a terminal and type:

sudo sed -i 's/NoDisplay=true/NoDisplay=false/g' /etc/xdg/autostart/*.desktop

Then launch the Gnome session properties from terminal:


Look for the appcenter launcher and uncheck it. It called:

appcenter -s

  • I didn't realize that it was running in the background so thanks for that. But that sed command is destructive to all items in *.desktop as written

    Thank you bitseater, it worked like a charm. @wolf, it is not, it just unhides the autostarted apps that elementary doesn't want you to see for cosmetic reasons.

    For elementary OS 5.0 Juno the first command should be killall io.elementary.appcenter Commented Mar 15, 2019 at 4:47

killall io.elementary.appcenter worked for me to kill the process
