Remove update notification in Unity indicator after xubuntu-desktop installation (12.04)

I'm on Ubuntu 12.04 using Unity. To try it out, I installed the xubuntu-desktop package. Ever since I have a orange or red update notification (see attachment) in my Unity indicator panel, telling me about recommended and security updates, respectively.

Q: How can I disable the notifications?

What i expect to happen: There is an option to show these updates when you press the update notification. I disabled it and thought it wouldn't show again after a reboot. In addition, I ran dconf-editor and manually checked if the option to hide updates is enabled.

What happened instead: The update notifications are still there, the only way to get rid of them is to do the updates.

Solution 1:

I don't know if this is a solution or just a workaround to your problem , but you can disable the update-notifier from startup applications. I think you will not receive anymore update-notifications then.

Open a terminal and give this command

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

Then try to disable it from startup applications and see if your problem solved.

OR

take a look inside /etc/xdg/lxsession and see if is something there related to update-notifier
